   2002 Dec 17 Philips Semiconductors Product data Octal transceiver with direction pin and 30 Ω series termination resistors (3-State) FEATURES 74ABT2245 DESCRIPTION • Octal bidirectional bus interface • 3-State buffers • Output capability: +12 mA / –32 mA • Latch-up protection exceeds 500 mA per Jedec Std 17 • ESD protection exceeds 2000 V per MIL STD 833 Method 3015 The 74ABT2245 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed. The 74ABT2245 device is an octal 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 an Output Enable (OE) input for easy cascading and a Direction (DIR) input for direction control. and 200 V per Machine Model • Power-up 3-State • Live insertion/extraction permitted • Same as 74ABT245-1 • Outputs include series resistance of 30 Ω, making external The 74ABT2245 is designed with 30 Ω series resistance in both the HIGH and LOW states of the output. This design reduces line noise in applications such as memory address drivers, clock drivers, and bus receivers/transmitters. The 74ABT2245 is the same as the 74ABT245-1. The part number has been changed to reflect industry standards. termination resistors unnecessary • Inputs are disabled during 3-State mode QUICK REFERENCE DATA SYMBOL CONDITIONS Tamb = 25 °C; GND = 0 V PARAMETER TYPICAL UNIT 3.9 ns tPLH tPHL Propagation delay An to Bn or Bn to An CL = 50 pF; VCC = 5 V CIN Input capacitance DIR, OE VI = 0 V or VCC 4 pF CI/O I/O pin capacitance Outputs disabled; VO = 0 V or VCC 7 pF ICCZ Total supply current Outputs disabled; VCC = 5.5 V 50 µA ORDERING INFORMATION PACKAGES TEMPERATURE RANGE PART NUMBER DWG NUMBER 20-Pin plastic SO –40 °C to +85 °C 74ABT2245D SOT163-1 20-Pin Plastic SSOP Type II –40 °C to +85 °C 74ABT2245DB SOT339-1 20-Pin Plastic TSSOP Type I –40 °C to +85 °C 74ABT2245PW SOT360-1 PIN CONFIGURATION PIN DESCRIPTION PIN NUMBER SYMBOL 1 DIR 18 B0 2, 3, 4, 5, 6, 7, 8, 9 A0 – A7 Data inputs/outputs (A side) 4 17 B1 Data inputs/outputs (B side) 16 B2 18, 17, 16, 15, 14, 13, 12, 11 B0 – B7 5 A4 6 15 B3 19 OE A5 7 14 B4 A6 8 13 B5 10 GND Ground (0 V) A7 9 12 B6 20 VCC Positive supply voltage DIR 1 20 VCC A0 2 19 OE A1 3 A2 A3 GND 10 11 B7 SA00121 2002 Dec 17 2 NAME AND FUNCTION Direction control input Output enable input (active-LOW) Philips Semiconductors Product data Octal transceiver with direction pin and 30 Ω series termination resistors (3-State) LOGIC SYMBOL 74ABT2245 FUNCTION TABLE INPUTS 1 DIR 19 OE 2 A0 18 B0 3 A1 17 B1 4 A2 A3 L L An = Bn Inputs L H Inputs Bn = An H X Z Z = High voltage level = Low voltage level = Don’t care = High impedance “off” state VCC 13 B5 8 A6 Bn SCHEMATIC OF EACH OUTPUT 14 A5 An B4 15 7 DIR B3 B2 6 A4 OE H L X Z 16 5 INPUTS/OUTPUTS 12 B6 9 A7 11 B7 SA00122 OUTPUT LOGIC SYMBOL IEEE/IEC 19 G3 3 EN1 (BA) 1 3 EN2 (AB) SA00237 1 2 2 18 3 17 4 16 5 15 6 14 7 13 8 12 9 11 SA00313 2002 Dec 17 3 Philips Semiconductors Product data Octal transceiver with direction pin and 30 Ω series termination resistors (3-State) 74ABT2245 ABSOLUTE MAXIMUM RATINGS1, 2 PARAMETER SYMBOL VCC IIK CONDITIONS RATING UNIT –0.5 to +7.0 V –18 mA –1.2 to +7.0 V VO < 0 V –50 mA output in Off or HIGH state –0.5 to +5.5 V output in LOW state 128 mA –65 to 150 °C DC supply voltage DC input diode current VI < 0 V voltage3 VI DC input IOK DC output diode current voltage3 VOUT DC output IOUT DC output current Tstg Storage temperature range NOTES: 1.
