description

These 9-bit latches feature three-state outputs

designed specifically for driving highly capacitive

or relatively low-impedance loads. They are

particularly suitable for implementing buffer

registers, I/O ports, bidirectional bus drivers, and

working registers.

SN74ALS29844 . . . DW or NT Package

(Top View)

The nine latches are transparent D-type. The

′ALS29843 has noninverting data (D) inputs. The

′ALS29844 has inverting D inputs.

PRE

A buffered output control (OC) input can be used

to place the nine outputs in either a normal logic

state (high or low 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 the

bus lines in a bus-organized system without need

for interface or pullup components.

CLR

GND

The output control (OC) does not affect the internal operation of the latches. Old data can be retained or new

data can be entered while the outputs are off.

The SN54ALS29843 is characterized for operation over the full military range of − 55°C to 125°C. The

SN74ALS29843 and SN74ALS29844 are characterized for operation from 0°C to 70°C.
