MC74HCT32A
Quad 2-Input OR Gate with
LSTTL Compatible Inputs
High−Performance Silicon−Gate CMOS
The MC74HCT32A is identical in pinout to the LS32. The device
inputs are compatible with Standard CMOS or LSTTL outputs.
Features
• Output Drive Capability: 10 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS and TTL
• Operating Voltage Range: 2.0 V to 6.0 V
• Low Input Current: 1 mA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance With the JEDEC Standard No. 7A Requirements
• Chip Complexity: 48 FETs or 12 Equivalent Gates
• These are Pb−Free Devices
Pinout: 14−Lead Packages (Top View)
