MC74HC161A: Presettable Counter
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.
特性- 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
- Pb-Free Packages are Available*
