Description
Can be configured to divide by 2, 8, and 16 Asynchronous reset Fanout (over temperature range) - Standard outputs: 10 LSTTL loads - Bus driver outputs: 15 LSTTL loads Wide operating temperature range: - 55°C to 125°C Balances propagation delay and transition times Signigicant power reduction compared to LSTTL logic ICs HC types - 2 V to 6 V operation - High noise immunity: NIL = 30%, NIH = 30% of VCC HCT types - 4.5 V to 5.5 V operation - Direct LSTTL input logic compatibility, VIL = 0.8 V (max), VIH = 2 V (min) - CMOS input compatibility, II ≤ 1 µA at VOL, VOH The CD74HC93 and CD74HCT93 are high-speed silicon-gate CMOS devices and are pin-compatible with low power Schottky TTL (LSTTL). These 4bit binary ripple counters consist of four flip-flops internally connected to provide a divide-by-two section and a divide-by-eight section.
