description

These 10-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.

The ten flip-flops are edge-triggered D-type

flip-flops. On the positive transition of the clock

(CLK) input, the devices provide true data at the

Q outputs.

A buffered output-enable (OE) input can be used

to place the ten outputs in either a normal logic

state (high or low logic levels) or a high-impe-

dance state. 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 need for interface or pullup

components.

NC – No internal connection

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.

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 SN54ABT821 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT821A is characterized for operation from –40°C to 85°C.
