MC74VHC1G125
Product Preview
Noninverting 3-State Buf fer
The MC74VHC1G125 is an advanced high speed CMOS
noninverting 3–state buffer fabricated with silicon gate CMOS
technology. It achieves high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining CMOS low power
dissipation.
The internal circuit is composed of three stages, including a buffered
3–state output which provides high noise immunity and stable output.
The MC74VHC1G125 input structure provides protection when
voltages up to 7V are applied, regardless of the supply voltage. This
allows the MC74VHC1G125 to be used to interface 5V circuits to 3V
circuits.
• High Speed: t
• Low Power Dissipation: I
• Power Down Protection Provided on Inputs
• Balanced Propagation Delays
• Pin and Function Compatible with Other Standard Logic Families
• Latchup Performance Exceeds 300mA
• ESD Performance: HBM > 1500V; MM > 200V
