MC74VHC244DTR2G Datasheet PDF - ON Semiconductor

●The MC74VHC244DTR2G is an advanced high speed CMOS octal Bus Buffer fabricated with silicon gate CMOS technology. The MC74VHC244 is a non-inverting 3-state buffer and has two active-low output enables. This device is designed to be used with 3-state memory address drivers. 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) = 3.9ns typical at VCC = 5V

● Low power dissipation - ICC = 4µA maximum at TA = 25°C

● High noise immunity - VNIH = VNIL = 28% VCC

● Latch-up performance exceeds 300mA

● Chip complexity - 136 FETs
