SCLS147F – DECEMBER 1982 – REVISED OCTOBER 2016 SNx4HC573A Octal Transparent D-Type Latches With 3-State Outputs
1 Features 3 Description The SNx4HC573A devices are octal transparent
D-type latches that feature 3-state outputs designed
specifically for driving highly capacitive or relatively
low-impedance loads. They are particularly suitable
for implementing buffer registers, I/O ports,
bidirectional bus drivers, and working registers. 1 Wide Operating Voltage Range from 2 V to 6 V
High-Current 3-State Outputs Drive Bus Lines
Directly up to 15 LSTTL Loads
Low Power Consumption: 80-ВµA Maximum ICC
Typical tpd = 21 ns
В±6-mA Output Drive at 5 V
Low Input Current: 1 ВµA (Maximum)
Bus-Structured Pinout While the latch-enable (LE) input is high, the
Q outputs respond to the data (D) inputs. When LE is
low, the outputs are latched to retain the data that
was set up. 2 Applications Device Information(1) Buffer Registers …
