HD74HC393 counters equivalent, dual 4-bit binary counters.
* High Speed Operation: tpd (A to QA) = 16 ns typ (CL = 50 pF)
* High Output Current: Fanout of 10 LSTTL Loads
* Wide Operating Voltage: VCC = 2 to 6 V
.
The HD74HC393 contain two 4-bit ripple carry binary counters, which can be cascaded to create a single divide-by-256 counter.
The HD74HC393 is incremented on the high to low transition (negative edge) of the clock input, and each has an independent c.
