High–Performance Silicon–Gate CMOS
The MC74HC158A 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 HC158A. A high level on the Output Enable input sets all four
Y outputs to a high level for the HC158A.
• 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

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.

PIN DESCRIPTIONS
INPUTS
A0–A3 (Pins 2,5,11,14)
Nibble A inputs. The data present on these pins is transferred to the outputs when the Select input is at a low level and
the Output Enable input is at a low level. The data is presented
to the outputs in inverted form for the HC158A.
B0–B3 (Pins 3,6,10,13)
Nibble B inputs. The data present on these pins is transferred to the outputs when the Select input is at a high level and
the Output Enable input is at a low level. The data is presented
to the outputs in inverted form for the HC158A.
OUTPUTS
Y0–Y3 (Pins 4,7,9,12)
Data outputs. The selected input nibble is presented at
these outputs when the Output Enable input is at a low level.
The data present on these pins is in its inverted form for the
HC158A. For the Output Enable input at a high level, the outputs are at a high level for the HC158A.
CONTROL INPUTS
Select (Pin 1)
Nibble select. This input determines the data word to be
transferred to the outputs. A low level on this input selects the
A inputs and a high level selects the B inputs.
Output Enable (Pin 15)
Output Enable input. A low level on thisinput allows the
selected data to be presented at the outputs. A high level on
this input sets all of the outputs to a high level for the HC158A.
