CD74HC93, CD74HCT93 SCHS138D - NOVEMBER 1998 - REVISED MARCH 2022 CD74HC93, CD74HCT93 High-Speed CMOS Logic 4-Bit Binary Ripple Counter 1 Features 2 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 pared to LSTTL logic ICs - HC types - 2 V to 6 V operation - High noise immunity: NIL = 30%, NIH = 30% of - HCT types - 4.5 V to 5.5 V operation - Direct LSTTL input logic patibility, VIL = 0.8 V (max), VIH = 2 V (min) - CMOS input patibility, II ≤ 1 µA at VOL, VOH The CD74HC93 and CD74HCT93 are high-speed silicon-gate CMOS devices and are pin-patible 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. Each section has a separate clock input (CP0 and CP1) to initiate state changes of the counter on the HIGH to LOW clock transition. State changes of the Qn outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and should not be used for clocks or strobes.
