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.

20 19

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.

9 10 11 12 13

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.
