MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
Quad 3-State D Flip-Flop with
Common Clock and Reset
High–Performance Silicon–Gate CMOS
The MC74HC173 is identical in pinout to the LS173. The device inputs are
compatible with standard CMOS outputs; with pullup resistors, they are
compatible with LSTTL outputs.
Data, when enabled, are clocked into the four D flip–flops with the rising
edge of the common Clock. When either or both of the Output Enable
Controls is high, the outputs are in a high–impedance state. This feature
allows the HC173 to be used in bus–oriented systems. The Reset feature is
asynchronous and active high.
Output Drive Capability: 15 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 2 to 6 V
Low Input Current: 1 µA
High Noise Immunity Characteristic of CMOS Devices
In Compliance with the Requirements Defined by JEDEC Standard
No. 7A
Chip Complexity 208 FETs or 52 Equivalent Gates
