74LV393PW,118

NXP  74LV393PW,118  芯片, 纹波二进制计数器, 90MHZ, TSSOP-14

The 74LV393PW is a 4-bit dual Binary Ripple Counter with individual clocks. It is pin and function compatible with 74HC393 and 74HCT393. Each counter features a clock input nCP\\, an overriding asynchronous master reset input nMR and 4 buffered parallel outputs nQ0 to nQ3. The counter advances on the high-to-low transition of nCP\\. A high on nMR clears the counter stages and forces the outputs low, independent of the state of nCP\\.

.

Accepts TTL input levels

.

Two master resets to clear each 4-bit counter individually

.

Complies with JEDEC standard No. 7A
