MC74HC390 Dual 4−Stage Binary Ripple Counter with ÷ 2 and ÷ 5 Sections High−Performance Silicon−Gate CMOS The MC54/74HC390 is identical in pinout to the LS390. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device cons.
Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 μA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No 7A
• Chip Complexity: 244 FETs or 61 Equivalent Gates
