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. 7A Requirements
• Chip Complexity: 72 FETs or 18 Equivalent Gates
• Pb−Free Packages are Available
