SN74ABT16373A-EP的产品详情：

The SN74ABT16373A-EP is a 16-bit transparent D-type latch with 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The SN74ABT16373A-EP is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

The SN74ABT16373A-EP can be used as two 8-bit latches or one 16-bit latch. 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 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 a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without need for interface or pullup components.

OE does not affect internal operations of the latch. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.

When V_CC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74ABT16373A-EP is characterized for operation from -55°C to 125°C.
