The MM74C90 and MM74C93 are 4-bit counters with wide voltage range, high noise immunity, and low power compatibility
The document describes two complementary MOS (CMOS) integrated circuits: the MM74C90 4-bit decade counter and the MM74C93 4-bit binary counter. These devices are constructed with N- and P-channel enhancement-mode transistors and feature a wide supply voltage range from 3V to 15V.
| Supply Voltage Range | 3V to 15V |
|---|---|
| Operating Temperature Range | -40°C to +85°C |
| Power Dissipation (Dual-In-Line) | 700 mW |
| Maximum Clock Frequency (VCC=5V) | 2 MHz |
| Package Type | 14-Lead Plastic Dual-In-Line Package (PDIP) |
The devices operate with a supply voltage ranging from 3V to 15V.
Yes, a separate flip-flop on the A-bit enables operation as a divide-by-2, 5, or 10 frequency counter.
The minimum pulse width for R01 or R02 inputs at VCC=5V is 600 ns.
