1 / 7 page © Semiconductor Components Industries, LLC, 2014 August, 2014 − Rev. 12 1 Publication Order Number: MC74HC157A/D MC74HC157A Quad 2-Input Data Selectors/Multiplexers High−Performance Silicon−Gate CMOS The MC74HC157A is identical in pinout to the LS157. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device routes 2 nibbles (A or B) to a single port (Y) as determined by the Select input. The data is presented at the outputs in noninverted form. A high level on the Output Enable input sets all four Y outputs to a low level. Features • Output Drive Capability: 10 LSTTL Loads • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 mA • High Noise Immunity Characteristic of CMOS Devices • In Compliance with the Requirements Defined by JEDEC Standard No. 7A • Chip Complexity: 82 FETs or 20.5 Equivalent Gates • NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable • These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant 2 5 11 14 3 6 10 13 4 7 9 12 1 15 A0 A1 A2 A3 B0 B1 B2 B3 Y0 Y1 Y2 Y3 SELECT OUTPUT ENABLE DATA OUTPUTS NIBBLE A INPUTS NIBBLE B INPUTS PIN 16 = VCC PIN 8 = GND Figure 1.
