MC74VHC125DTR2G

The MC74VHC125DTR2G is a quad high speed CMOS Bus Buffer with 3-state control inputs. It is fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent bipolar Schottky TTL while maintaining CMOS low power dissipation. The MC74VHC125 requires the 3-state control input (OE) to be set high to place the output into the high impedance state. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems.

• Power down protection provided on inputs
• Balanced propagation delays
• Pin and function compatible with other standard logic families
• Designed for 2 to 5.5V operating range
• High speed - Propagation delay (tpd) = 3.8ns typical at VCC = 5V
• Low power dissipation - ICC = 1μA maximum at TA = 25°C
• High noise immunity - VNIH = VNIL = 28% VCC
• Latch-up performance exceeds 300mA
• Chip complexity - 72 FETs or 18 equivalent gates
