SN74LS93N 4-bit Binary Counter Logic IC

The SN74LS93N, SN74HC93N, SN7493 are silicon-gate CMOS devices and are pin-compatible with low power Schottky TTL (LSTTL). These 4- bit 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.

The 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.

Features:

1. Can be configured to divide by 2, 8, and 16
2. Asynchronous reset
3. Fanout (over temperature range) – Standard outputs: 10 LSTTL loads – Bus driver outputs: 15 LSTTL loads
4. Wide operating temperature range: – 55°C to 125°C
5. Balances propagation delay and transition times
6. Signigicant power reduction compared to LSTTL logic ICs
7. HC types – 2 V to 6 V operation – High noise immunity: NIL = 30%, NIH = 30% of VCC
8. 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
