Product Summary
The SN74HC373PWR is a 8-bit latch. It features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The SN74HC373PWR is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight latches of the SN74HC373PWR are transparent D-type latches. While 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 that were set up at the D inputs.
