MC74HC240A_14 Datasheet, PDF (1/7 Pages) ON Semiconductor – Octal 3-State Inverting Buffer/Line Driver/Line Receiver

MC74HC240A
Octal 3-State Inverting
Buffer/Line Driver/Line
Receiver
High−Performance Silicon−Gate CMOS
The MC74HC240A is identical in pinout to the LS240. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
This octal noninverting buffer/line driver/line receiver is designed
to be used with 3−state memory address drivers, clock drivers, and
other sub−oriented systems. The device has inverting outputs and two
active−low output enables.
The HC240A is similar in function to the HC244A.
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 mA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard
No. 7 A
• Chip Complexity: 120 FETs or 30 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 and are RoHS Compliant
