1 / 9 page tm May 2007 ©1997 Fairchild Semiconductor Corporation www.fairchildsemi.com 74VHCT244A Rev. 1.3 74VHCT244A Octal Buffer/Line Driver with 3-STATE Outputs Features ■ High Speed: tPD = 5.9ns (Typ.) at VCC = 5V ■ Power down protection is provided on inputs and outputs ■ Low power dissipation: ICC = 4µA (Max.) @ TA = 25°C ■ Pin and function compatible with 74HCT244 General Description The VHCT244A is an advanced high speed CMOS octal bus transceiver fabricated with silicon gate CMOS tech- nology. It achieves high speed operation similar to equiv- alent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHCT244A is a non- inverting 3-STATE buffer having two active-LOW output enables. This device is designed to be used as 3-STATE memory address drivers, clock drivers, and bus oriented transmitter/receivers. Protection circuits ensure that 0V to 7V can be applied to the input and output(1) pins without regard to the supply voltage. These circuits prevent device destruction due to mismatched supply and input/output voltages. This device can be used to interface 5V to 3V systems and two supply systems such as battery back up. Note: 1. Outputs in OFF-State Ordering Information Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering number. Pb-Free package per JEDEC J-STD-020B.
