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, parity bus interfacing, 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 (CLK) input. Taking CLKEN high disables the clock buffer, latching the outputs. The

′ALS29823 have noninverting data (D) inputs. Taking the clear (CLR) input low causes the nine Q outputs to

go low independently of the clock.

Abufferedoutput-enable(OE)inputplacesthenineoutputsineitheranormallogicstate(highorlowlogiclevels)

or a high-impedance state. The outputs also are 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.

OE does not affect the internal operation of the flip-flops. Old data can be retained or new data can be entered

while the outputs are in the high-impedance state.

The SN54ALS29823 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74ALS29823 is characterized for operation from 0°C to 70°C.
