54FCT373 Octal Transparent Latch with TRI-STATE Outputs
October 1999
54FCT373
Octal Transparent Latch with TRI-STATE
廬
Outputs
General Description
The 鈥橣CT373 consists of eight latches with TRI-STATE out-
puts for bus organized system applications. The flip-flops ap-
pear 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
TRI-STATE outputs for bus interfacing
TTL input and output level compatible
CMOS power consumption
Output sink capability of 32 mA, source capability of
12 mA
