CS3730ACO

DESCRIPTION

The UT54ACS373 and the UT54ACTS373 are 8-bit latches with three-state outputs designed for driving highly capacitive or relatively low-impedance loads. The device is suitable for buffer registers, I/O ports, and bidirectional bus drivers.
The eight latches are transparent D latches. While the enable (C) is high the Q outputs will follow the data (D) inputs. When the enable is taken low, the Q outputs will be latched at the levels that were set up at the D inputs.
An output-control input (OC) places the eight outputs in either a normal logic state (high or low logic levels) or a high-impedance state. The high-impedance third state and increased drive provide the capability to drive the bus line in a bus-organized system without need for interface or pull-up components.
The output control OC does not affect the internal operations of the latches. Old data can be retained or new data can be entered while the outputs are off.
The devices are characterized over full military temperature range of -55°C to +125°C.
