description

These 8-bit latches feature 3-state outputs

designed specifically for driving highly capacitive

or relatively low-impedance loads. The devices

are particularly suitable for implementing buffer

registers, I/O ports, bidirectional bus drivers, and

working registers.

The eight latches are D-type transparent latches.

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 logic

levels set up at the D inputs.

A buffered output-enable (OE) input can be used

to place the eight outputs in either a normal logic

state (high or low logic levels) or the

high-impedance state. In the high-impedance

state, the outputs neither load nor drive the bus

lines significantly. The high-impedance state and

increased drive provide the capability to drive bus

lines in bus-organized systems without need for

interface or pullup components.

OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered

while the outputs are in the high-impedance state.

The SN54ACT373 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ACT373 is characterized for operation from –40°C to 85°C.
