description

This 8-bit latch features 3-state outputs designed specifically for driving highly capacitive or relatively

low-impedance loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus

drivers, and working registers.

The eight latches of the SN64BCT373 are transparent D-type latches. While the latch-enable (LE) input is high,

the Q outputs follow the data (D) inputs. When the enable is taken low, the Q outputs are latched at the levels

that were 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 a high-impedance state. In the high-impedance state the outputs neither load nor drive

the bus lines significantly. The high-impedance impedance state and increased drive provide the capability to

drive bus lines without need for interface or pullup components.

The output-enable (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 off.

The outputs are in a high-impedance state during power up and power down while the supply voltage is less

than approximately 3 V.

The SN64BCT373 is characterized for operation from −40°C to 85°C and 0°C to 70°C.
