description

This 8-bit latch features 3-state outputs designed specificallyfor driving highly-capacitive or relatively low-impedance loads. Itis particularly suitable for implementing buffer registers, I/Oports, bidirectional bus drivers, and working registers.

The eight latches of the 74ACT11373 are transparent D-typelatches. While the latch-enable (LE) input is high, the Q outputsfollow the data (D) inputs. When the enable is taken low, the Qoutputs are latched at the levels that were set up at the D inputs.

A buffered output-enable input can be used to place the eight outputs in either a normal logicstate (high or low logic levels) or a high-impedance state. In thehigh-impedance state, the outputs neither load nor drive the buslines significantly. The high-impendance third state and increaseddrive provide the capability to drive the bus lines in abus-organized system without need for interface or pullup components.

does not affectthe internal operations of the latches. Old data can be retained ornew data can be entered while the outputs are off.

The 74ACT11373 is characterized for operation from -40°C to85°C.
