1 / 21 page SN54HCT373, SN74HCT373 OCTAL TRANSPARENT D-TYPE LATCHES WITH 3-STATE OUTPUTS SCLS009D – MARCH 1984 – REVISED AUGUST 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Operating Voltage Range of 4.5 V to 5.5 V D High-Current 3-State True Outputs Can Drive Up To 15 LSTTL Loads D Low Power Consumption, 80-µA Max ICC D Typical tpd = 21 ns D ±6-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Inputs Are TTL-Voltage Compatible D Eight High-Current Latches in a Single Package D Full Parallel Access for Loading description/ordering information These 8-bit latches 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. The eight latches of the ’HCT373 devices are transparent D-type latches. While the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels that were set up at the D inputs.
