INTEGRATED CIRCUITS 74ABT162245A 74ABTH162245A 16-Bit bus transceiver with 30Ω series termination resistors (3-State) Product specification Supersedes data of 1996 Nov 20 IC23 Data Handbook 1998 Feb 25 Philips Semiconductors Philips Semiconductors Product specification 16-bit bus transceiver with 30Ω series termination resistors (3-State) 74ABT162245A 74ABTH162245A FEATURES • 16-bit bidirectional bus interface • Power-up 3-State • Multiple VCC and GND pins minimize switching noise • 3-State buffers • Output capability: +12mA/–32mA • Latch-up protection exceeds 500mA per JEDEC Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200V per Machine Model DESCRIPTION The 74ABT162245A high-performance BiCMOS device combines low static and dynamic power dissipation with high speed. The 74ABT162245A device is a 16-bit transceiver featuring non-inverting 3-State bus compatible outputs in both send and receive directions. The control function implementation minimizes external timing requirements. The device features two Output Enable (1OE, 2OE) inputs for easy cascading and two Direction (1DIR, 2DIR) inputs for direction control. The 74ABT162245A is designed with 30 ohm series resistance in both the upper and lower output structures on both A and B ports. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receiver/transmitters. The 74ABT162245A is the same as the 74ABT16245A-1. The part number has been changed to reflect industry standards Two options are available, 74ABT162245A which does not have the bus hold feature and the 74ABTH162245A which incorporates the bus hold feature. CONDITIONS Tamb = 25°C; GND = 0V • Same part as 74ABT16245A-1 • 74ABTH162245A incorporates bus hold data inputs which eliminate the need for external pull-up resistors to hold unused inputs • Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs QUICK REFERENCE DATA SYMBOL tPLH tPHL CIN CI/O ICCZ ICCL PARAMETER Propagation delay nAx to nBx or nBx to nAx Input capacitance I/O pin capacitance Quiescent supply current su current TYPICAL 2.0 3.0 3 7 300 10 UNIT ns pF pF nA mA CL = 50pF; VCC = 5V VI = 0V or VCC VO = 0V or VCC; 3-State Outputs disabled; VCC = 5.5V Outputs Low; VCC = 5.5V ORDERING INFORMATION PACKAGES 48-Pin Plastic SSOP Type III 48-Pin Plastic TSSOP Type II 48-Pin Plastic SSOP Type III 48-Pin Plastic TSSOP Type II TEMPERATURE RANGE –40°C to +85°C –40°C to +85°C –40°C to +85°C –40°C to +85°C OUTSIDE NORTH AMERICA 74ABT162245A DL 74ABT162245A DGG 74ABTH162245A DL 74ABTH162245A DGG NORTH AMERICA BT162245A DL BT162245A DGG BH162245A DL BH162245A DGG DWG NUMBER SOT370-1 SOT362-1 SOT370-1 SOT362-1 1998 Feb 25 2 853-1772 19018 Philips Semiconductors Product specification 16-bit bus transceiver with 30Ω series termination resistors (3-State) 74ABT162245A 74ABTH162245A PIN CONFIGURATION 1DIR 1B0 1B1 GND 1B2 1B3 VCC 1B4 1B5 1 2 3 4 5 6 7 8 9 48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 1OE 1A0 1A1 GND 1A2 1A3 VCC 1A4 1A5 GND 1A6 1A7 2A0 2A1 GND 2A2 2A3 VCC 2A4 2A5 GND 2A6 2A7 2OE LOGIC SYMBOL 1DIR 1 48 1A0 47 2 2DIR 1OE 1B0 2A0 36 24 25 13 2OE 2B0 1A1 46 3 1B1 2A1 35 14 2B1 1A2 44 5 1B2 2A2 33 16 2B2 GND 10 1B6 11 1B7 12 2B0 13 2B1 14 GND 15 2B2 16 2B3 17 VCC 18 2B4 19 2B5 20 GND 21 1A3 43 6 1B3 2A3 32 17 2B3 1A4 41 8 1B4 2A4 30 19 2B4 1A5 40 9 1B5 2A5 29 20 2B5 1A6 38 11 1B6 2A6 27 22 2B6 1A7 37 12 1B7 2A7 26 23 2B7 2B6 22 2B7 23 2DIR 24 SA00021 FUNCTION TABLE INPUTS nOE nDIR L H X INPUTS/OUTPUTS nAx A=B Inputs Z nBx Inputs B=A Z SA00020 PIN DESCRIPTION SYMBOL 1DIR, 2DIR PIN NUMBER 1, 24 47, 46, 44, 43 41, 40, 38, 37 36, 35, 33, 32 30, 29, 27, 26 2, 3, 5, 6 8, 9, 11, 12 13, 14, 16, 17 19, 20, 22, 23 48, 25 4, 10, 15, 21 28, 34, 39, 45 7, 18, 31, 42 NAME AND FUNCTION Direction control inputs (Active-High) H L X Z L L H 1A0 – 1A7, 2A0 – 2A7 Data inputs/outputs (A side) = HIGH voltage level = LOW voltage level = D0n’t care = High impedance “off” state 1B0 – 1B7 2B0 – 2B7 1OE, 2OE GND VCC Data inputs/outputs (B side) Output enables Ground (0V) Positive supply voltage 1998 Feb 25 3 Philips Semiconductors Product specification 16-bit bus transceiver with 30Ω series termination resistors (3-State) 74ABT162245A 74ABTH162245A LOGIC SYMBOL (IEEE/IEC) 48 1 G3 3 EN1 (BA) 3 EN2 (AB) 25 24 G6 6 EN4 (BA) 6 EN5 (AB) 47 ∇1 2∇ 46 44 43 41 40 38 37 36 ∇4 5∇ 35 33 32 30 29 27 26 14 16 17 19 20 22 23 3 5 6 8 9 11 12 13 2 SCHEMATIC OF EACH OUTPUT VCC 27Ω OUTPUT 27Ω GND SA00042 SA00022 1998 Feb 25 4 Philips Semiconductors Product specification 16-bit bus transceiver with 30Ω series termination resistors (3-State) 74ABT162245A 74ABTH162245A ABSOLUTE MAXIMUM RATINGS1, 2 SYMBOL VCC IIK VI IOK VOUT IO OUT Tstg PARAMETER DC supply voltage DC input diode current DC input voltage3 VO < 0 output in Off or High state output in Low state DC output current output current output in High state Storage temperature range –64 –65 to 150 °C VI < 0 CONDITIONS RATING –0.5 to +7.0 –18 –1.2 to +7.0 –50 –0.5 to +5.5 128 mA UNIT V mA V mA V DC output diode current DC output voltage3 NOTES: 1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. 2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C. 3. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

This parameter is valid for any VCC between 0V and 2.1V, with a transition time of up to 10msec. From VCC = 2.1V to VCC = 5 ±10% a transition time of up to 100 µsec is permitted. 4. This is the bus hold overdrive current required to force the input to the opposite logic state. 1998 Feb 25 6 Philips Semiconductors Product specification 16-bit bus transceiver with 30Ω series termination resistors (3-State) 74ABT162245A 74ABTH162245A AC CHARACTERISTICS GND = 0V; tR = tF = 2.5ns; CL = 50pF, RL = 500Ω LIMITS SYMBOL PARAMETER WAVEFORM Min tPLH tPHL tPZH tPZL tPHZ tPLZ Propagation delay nAx to nBx or nBx to nAx Output enable time to High and Low level Output disable time from High and Low level 1 2 2 1.0 1.5 1.5 2.0 1.7 1.5 Tamb = +25°C VCC = +5.0V Typ 2.0 3.0 3.1 5.0 3.5 3.2 Max 3.3 4.5 4.3 6.1 4.8 4.5 Tamb = –40°C to +85°C VCC = +5.0V ±0.5V Min 1.0 1.5 1.5 2.0 1.7 1.5 Max 3.5 4.9 5.0 7.0 5.4 4.9 ns ns ns UNIT AC WAVEFORMS VM = 1.5V, VIN = GND to 3.0V 3V nOE INPUT 1.5V INPUT 0V tPLH tPHL VOH 1.5V OUTPUT VOL tPZH tPHZ 1.5V OUTPUT VM VOL + 0.3V VOL VOH VOH – 0.3V VM OUTPUT 0V tPZL tPLZ 3.5V 1.5V VM VM SA00028 Waveform 1.
