74ABT823DB

Philips Semiconductors Product specification 9-bit D-type flip-flop with reset and enable (3-State) 74ABT823 FEATURES flip-flops • High speed parallel registers with positive edge-triggered D-type • Ideal where high speed, light loading, or increased fan-in are required with MOS microprocessors DESCRIPTION The 74ABT823 Bus interface Register is designed to eliminate the extra packages required to buffer existing registers and provide extra data width for wider data/address paths of buses carrying parity. The 74ABT823 is a 9-bit wide buffered register with Clock Enable (CE) and Master Reset (MR) which are ideal for parity bus interfacing in high microprogrammed systems. The register is fully edge-triggered. The state of each D input, one set-up time before the Low-to-High clock transition is transferred to the corresponding flip-flop’s Q output. • Output capability: +64mA/–32mA • Latch-up protection exceeds 500mA per Jedec Std 17 • ESD protection exceeds 2000 V per MIL STD 883 Method 3015 and 200 V per Machine Model • Power-up 3-State • Power-up Reset QUICK REFERENCE DATA SYMBOL tPLH tPHL CIN COUT ICCZ PARAMETER Propagation delay CP to Qn Input capacitance Output capacitance Total supply current CONDITIONS Tamb = 25°C; GND = 0V CL = 50pF; VCC = 5V VI = 0V or VCC Outputs disabled; VO = 0V or VCC Outputs disabled; VCC =5.5V TYPICAL 4.4 4 7 500 UNIT ns pF pF nA ORDERING INFORMATION PACKAGES 24-Pin Plastic DIP 24-Pin plastic SO 24-Pin Plastic SSOP Type II 24-Pin Plastic TSSOP Type I 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 74ABT823 N 74ABT823 D 74ABT823 DB 74ABT823 PW NORTH AMERICA 74ABT823 N 74ABT823 D 74ABT823 DB 74ABT823PW DH DWG NUMBER SOT222-1 SOT137-1 SOT340-1 SOT355-1 PIN CONFIGURATION PIN DESCRIPTION PIN NUMBER SYMBOL OE D0-D8 Q0-Q8 CP CE MR GND VCC FUNCTION Output enable input (active-Low) Data inputs Data outputs Clock pulse input (active rising edge) Clock enable input (active-Low) Master reset input (active-Low) Ground (0V) Positive supply voltage OE D0 D1 D2 D3 D4 D5 D6 D7 1 2 3 4 5 6 7 8 9 24 23 22 21 20 19 18 17 16 15 14 13 TOP VIEW VCC Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 CE CP 1 2, 3, 4, 5, 6, 7, 8, 9, 10 23, 22, 21, 20, 19,18, 17, 16, 15 13 14 11 12 24 D8 10 MR 11 GND 12 SA00227 1995 Sep 06 1 853–1617 15703 Philips Semiconductors Product specification 9-bit D-type flip-flop with reset and enable (3-State) 74ABT823 LOGIC SYMBOL LOGIC SYMBOL (IEEE/IEC) 1 11 2 3 4 5 6 7 8 9 10 14 13 D0 D1 D2 D3 D4 D5 D6 D7 D8 13 14 11 1 CP CE MR OE Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 Q8 2 3 4 5 6 7 23 22 21 20 19 18 17 16 15 8 9 10 EN R G1 1C2 2D 23 22 21 20 19 18 17 16 15 SA00228 SA00229 FUNCTION TABLE INPUTS OE L L L L H H h L l MR L H H H X CE X L L H X CP X ↑ ↑ ↑ X Dn X h l X X OUTPUTS Q0 – Q8 L H L NC Z Hold High impedance NC X Z ↑ ↑ = = = = = No change Don’t care High impedance “off” state Low to High clock transition Not a Low-to-High clock transition Clear Load and read data OPERATING MODE = High voltage level = High voltage level one set-up time prior to the Low-to-High clock transition = Low voltage level = Low voltage level one set-up time prior to the Low-to-High clock transition LOGIC DIAGRAM 14 CE D0 2 13 CP CP D D CP D CP D CP D CP D CP D CP D CP D CP D1 3 D2 4 D3 5 D4 6 D5 7 D6 8 D7 9 D8 10 R Q R Q R Q RR Q R Q R Q R Q R Q R Q 11 MR 1 OE 23 Q0 22 Q1 21 Q2 20 Q3 19 Q4 18 Q5 17 Q6 16 Q7 15 Q8 SA00230 1995 Sep 06 2 Philips Semiconductors Product specification 9-bit D-type flip-flop with reset and enable (3-State) 74ABT823 ABSOLUTE MAXIMUM RATINGS1, 2 SYMBOL VCC IIK VI IOK VOUT IOUT Tstg PARAMETER DC supply voltage DC input diode current DC input voltage3 VO < 0 output in Off or High state output in Low state VI < 0 CONDITIONS RATING –0.5 to +7.0 –18 –1.2 to +7.0 –50 –0.5 to +5.5 128 –65 to 150 UNIT V mA V mA V mA °C DC output diode current DC output voltage3 DC output current Storage temperature range 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.

Not more than one output should be tested at a time, and the duration of the test should not exceed one second. 2. This is the increase in supply current for each input at 3.4V. 3. For valid test results, data must not be loaded into the flip-flops (or latches) after applying the power. 4. This parameter is valid for any VCC between 0V and 2.1V with a transition time of up to 10msec. For VCC = 2.1V to VCC = 5V " 10%, a transition time of up to 100µsec is permitted.
