HD74LV373A
Octal D-type Transparent Latches with 3-state Outputs
ADE-205-274 (Z)
1st Edition
April 1999
Description
The HD74LV373A has eight D type latches with three state outputs in a 20 pin package. When the latch
enables input is high, the Q outputs will follow the D inputs. When the latch enables goes low, data at the
D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is
applied to the output control input, all outputs go to a high impedance state, regardless of what signals are
present at the other inputs and the state of the storage elements. Low-voltage and high-speed operation is
suitable for the battery-powered products (e.g., notebook computers), and the low-power consumption
extends the battery life.
