Description
Manufacturer
National Semiconductor
Datasheet
C 1995 National Semiconductor Corporation
54F 74F373
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
