MC74HC368A Datasheet, PDF (1/7 Pages) ON Semiconductor – Hex 3-State Inverting Buffer

MC74HC368A
Hex 3-State Inverting
Buffer with Separate 2-Bit
and 4-Bit Sections
High−Performance Silicon−Gate CMOS
The MC74HC368A is identical in pinout to the LS368. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
This device is arranged into 2−bit and 4−bit sections, each having its
own active−low Output Enable. When either of the enables is high, the
affected buffer outputs are placed into high−impedance states. The
HC368A has inverting outputs.
Features
• Output Drive Capability: 15 LSTTL Loads
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2 to 6 V
• Low Input Current: 1 mA
• High Noise Immunity Characteristic of CMOS Devices
• These are Pb−Free Devices
