High–Performance Silicon–Gate CMOS
The MC54/74HC158 is identical in pinout to the LS158. The device
inputs are compatible with Standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
These devices route 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in inverted
form for the HC158. A high level on the Output Enable input sets all four Y
outputs to a high level for the HC158.
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 2 to 6V
• Low Input Current: 1µA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance With the JEDEC Standard No. 7A Requirements
• Chip Complexity: 74 FETs or 18.5 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.
