Overview
MC74HC125A, MC74HC126A Quad 3-State Noninverting Buffers High−Performance Silicon−Gate CMOS The MC74HC125A and MC74HC126A are identical in pinout to the LS125 and LS126.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC125A and HC126A noninverting buffers are designed to be used with 3−state memory address drivers, clock drivers, and other bus−oriented systems.
The devices have four separate output enables that are active−low (HC125A) or active−high (HC126A).
Features • Output Drive Capability: 15 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 JEDEC Standard No.
7 A Requirements • Chip Complexity: 72 FETs or 18 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 LOGIC DIAGRAM HC125A Active−Low Output Enables HC126A Active−High Output Enables A1 2 3 Y1 A1 2 3 Y1 OE1 1 5 A2 OE1 1 6 5 Y2 A2 6 Y2 OE2 4 9 A3 OE2 4 8 Y3 A3 9 8 Y3 OE3 10 12 A4 13 OE4 OE3 10 11 12 Y4 A4 13 OE4 PIN 14 = VCC PIN 7 = GND 11 Y4 © Semiconductor Components Industries, LLC, 2014 1 August, 2014 − Rev.
