74F533

Octal Transparent Latch with 3-STATE Outputs

General Description

The 74F533 consists of eight latches with 3-STATE outputs

for bus organized system applications. The flip-flops

appear transparent to the data when Latch Enable (LE) is

HIGH. When LE is LOW, the data that meets the setup

times is latched. Data appears on the bus when the Output

Enable (OE) is LOW. When OE is HIGH the bus output is in

the high impedance state. The 74F533 is the same as the

74F373, except that the outputs are inverted.

Features

s Eight latches in a single package

s 3-STATE outputs for bus interfacing

s Inverted version of the 74F373

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
