  • Member of the Texas Instruments Widebus+™ Family
  • Operates from 1.65 V to 3.6 V
  • Inputs accept voltages to 5.5 V
  • Max tpd of 4.2 ns at 3.3 V
  • Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, TA = 25°C

This 32-bit transparent D-type latch is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVCH32373A is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as four 8-bit latches, two 16-bit latches, or one 32-bit latch. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the D inputs.
