MC74HC161A, MC74HC163A Presettable Counters High–Performance Silicon–Gate CMOS The MC74HC161A and HC163A are identical in pinout to the LS161 and LS163. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. The HC161A and HC163A are programmable 4–bit binary counters with asynchronous and synchronous reset, respectively. http://onsemi.com MARKING DIAGRAMS 16 16 1 Device Count Mode Binary Binary Reset Mode HC161A HC163A Asynchronous Synchronous Output Drive Capability: 10 LSTTL Loads Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 192 FETs or 48 Equivalent Gates PDIP–16 N SUFFIX CASE 648 MC74HC16xAN AWLYYWW 1 16 16 1 SO–16 D SUFFIX CASE 751B A WL YY WW HC16xA AWLYWW 1 = Assembly Location = Wafer Lot = Year = Work Week ORDERING INFORMATION Device MC74HC16xAN MC74HC16xAD MC74HC16xADR2 14 13 12 11 Package PDIP–16 SOIC–16 SOIC–16 Shipping 2000 / Box 48 / Rail 2500 / Reel LOGIC DIAGRAM P0 PRESET DATA INPUTS P1 P2 P3 3 4 5 6 Q0 Q1 Q2 Q3 RIPPLE CARRY OUT BCD OR BINARY OUTPUT PIN ASSIGNMENT RESET CLOCK P0 P1 P2 P3 ENABLE P 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC RIPPLE CARRY OUT Q0 Q1 Q2 Q3 ENABLE T LOAD CLOCK 2 15 RESET LOAD COUNT ENABLES ENABLE P ENABLE T 1 9 7 10 Clock ……
