Description

This SN74LVC843A 9-bit bus-interface D-type latch is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVC843A is 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 SN74LVC843A nine latches are transparent D-type latches. The device has noninverting data (D) inputs and provides true data at its outputs.

SN74LVC843A A buffered output-enable (OE) input can be used to place the nine outputs in either a normal logic state (high or low logic levels) or a high-impedance state. The outputs are also in the high-impedance state during power-up and power-down conditions. The outputs remain in the high-impedance state while the device is powered down. 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 without interface or pullup components. 

SN74LVC843A OE does not affect the internal operations of the latch. Previously stored data can be retained or new data can be entered while the outputs are in the high-impedance state. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.

To ensure the high-impedance state during power up or power down, SN74LVC843A OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74LVC843A is characterized for operation from 40°C to 85°C.
