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 pull–up 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 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 mA 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 MC74HC16xAN AWLYYWW 1 PDIP–16 N SUFFIX CASE 648 16 16 1 HC16xA AWLYWW 1 RESET CLOCK P0 P1 P2 P3 ENABLE P GND 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 SO–16 D SUFFIX CASE 751B 16 16 1 TSSOP–16 DT SUFFIX CASE 948F HC 16xA ALYW 1 Figure 1.
