Octal Transparent Latch with TRI-STATE Outputs
General Description
The ’F373 consists of eight latches with TRI-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
Features
Y Eight latches in a single package
Y TRI-STATE outputs for bus interfacing
Y Guaranteed 4000V minimum ESD protection

Functional Description
The ’F373 contains eight D-type latches with TRI-STATE
output buffers When the Latch Enable (LE) input is HIGH
data on the Dn inputs enters the latches In this condition
the latches are transparent i e a latch output will change
state each time its D input changes When LE is LOW the
latches store the information that was present on the D in-
puts a setup time preceding the HIGH-to-LOW transition of
LE The TRI-STATE buffers are controlled by the Output
Enable (OE) input When OE is LOW the buffers are in the
bi-state mode When OE is HIGH the buffers are in the high
impedance mode but this does not interfere with entering
new data into the latches
