ML4335

Quad Latch

(Open Collector)

This monolithic device consists of four latch circuits with open

collector outputs common Strobe input, and output enable input.

The output of each latch will follow the data input when the

Strobe input is in a logical “1” state. When the Strobe is in a log-

ical “0” state, the latch will store the logic state of the data input

just prior to the change of the Strobe from a “1” level to a “0”

level.

The open collector outputs make this device useful for bussing

or wire ORing outputs together. Two 5.0 k ohm resistor are avail-

able in the package to provide the passive pullup function in

wired–OR or bussed operation. The output enable is useful

where it is desirable to gate information out of the latches

according to a predetermined timing scheme.

Input Loading Factor (MTTL 1 Loads):

Data Input (Strobe High) –

4335 = 4.2

Data Input (Strobe Low) –

4335 = 1.1

Output Enable –

4335 = 4.0

Output Loading Factor ( TTL 1 Loads):

4335 = 7 (1OL = 9.3 mAdc)
