description

These 9-bit flip-flops feature 3-state outputs

designed specifically for driving highly capacitive

or relatively low-impedance loads. They are

particularly suitable for implementing wider buffer

registers, I/O ports, bidirectional bus drivers with

parity, and working registers.

With the clock-enable (CLKEN) input low, the nine

D-type edge-triggered flip-flops enter data on the

low-to-high transitions of the clock. TakingCLKEN

high disables the clock buffer, thus latching the

outputs. Taking the clear (CLR) input low causes

the nine Q outputs to go low, independently of the

clock.

NC – No internal connection

A buffered output-enable (OE) input can be used to place the nine outputs in either a normal logic state (high

or low logic level) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive

without need for interface or pullup components.

When V

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

the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT823 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT823 is characterized for operation from –40°C to 85°C.
