Octal Transparent Latch with TRI-STATE Outputs
É
General Description
Features
Y
Eight latches in a single package
The ’F533 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. The ’F533 is the same as the ’F373, ex-
cept that the outputs are inverted.
Y

Functional Description
The ’F533 contains eight D-type latches with TRI-STATE
output buffers. When the Latch Enable (LE) input is HIGH,
data on the D inputs enters the latches. In this condition
n
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.
