74HCT125
QUADRUPLE 3-STATE BUFFERS OE LOW
Description
The 74HCT125 provides provides four independent buffer gates with
3-state outputs. Each buffer has a separate enable pin that if driven
with a high logic level places the corresponding output in the high
impedance state. The device is designed for operation with a power
supply range of 4.5V to 5.5V.
Features
• Wide Supply Voltage Range from 4.5V to 5.5V
• Pin Compatible with Low Power Schottky (LSTTL)
• Inputs Are TTL Voltage Level Compatible
• Sinks or Sources 4mA at V_CC = 4.5V
• CMOS Low Power Consumption
• Schmitt Trigger Action at All Inputs
• ESD Protection Exceeds JESD 22
ƒ 200-V Machine Model (A115-A)
