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 t he common Clock. W hen either or b oth 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

NOTE: Information on typical parametric values can be found in Chapter 2 of the Motorola High–Speed CMOS Data Book (DL129/D).

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance cir­cuit. For proper operation, Vin and
V

out

should be constrained to the

range GND v (Vin or V

out

) v VCC.

Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.
