74LV393
Dual 4-bit binary ripple counter
Rev. 5 — 8 December 2015
Product data sheet
1. General description
The 74LV393 is a low–voltage Si-gate CMOS device and is pin and function compatible
with 74HC393 and 74HCT393.
The 74LV393 is a dual 4-stage binary ripple counter. 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.
2. Features and benefits
Optimized for low voltage applications: 1.0 V to 3.6 V
Accepts TTL input levels between V
CC
= 2.7 V and V
CC

Typical V
OLP
(output ground bounce) 0.8 V at V
CC
= 3.3 V, T
amb

C
Typical V
OHV
(output V

Two 4-bit binary counters with individual clocks
Divide-by any binary module up to 28 in one package
Two master resets to clear each 4-bit counter individually
Complies with JEDEC standard no. 7A
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
