Dual 4-bit binary ripple counter

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.

Features

  • Optimized for low voltage applications: 1.0 V to 3.6 V
  • Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V
  • Typical VOLP (output ground bounce) 0.8 V at VCC = 3.3 V; Tamb = 25 °C
  • Typical VOHV (output VOH undershoot) 2 V at VCC = 3.3 V; Tamb = 25 °C
  • 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
