Part Description: 74VHCT245A Octal Buffer Line Driver with 3-STATE Outputs

Part Details:

74VHCT245A Octal Buff May 2007 74VHCT245A tm Octal Buffer/Line Driver with 3-STATE Outputs Features General Description High Speed: t = = PD 5.4ns (Typ.) at VCC 5V The VHCT245A is an advanced high speed CMOS octal er/Line Driver with 3-ST Power Down Protection on Inputs and Outputs bus transceiver fabricated with silicon gate CMOS tech- Low Power Dissipation: I = µ = nology. It achieves high speed operation similar to equiv- CC 4 A (Max.) @ TA 25°C alent Bipolar Schottky TTL while maintaining the CMOS Pin and Function Compatible with 74HCT245 low power dissipation. The VHCT245A is intended forbidirectional asynchronous communication betweendata busses. The direction of data transmission is deter-mined by the level of the T/R input. The enable input canbe used to disable the device so that the busses areeffectively isolated. Protection circuits ensure that 0V to 7V can be applied tothe input and output(1) pins without regard to the supplyvoltage. These circuits prevent device destruction due to A mismatched supply and input/output voltages. This TE Outputs device can be used to interface 5V to 3V systems andtwo supply systems such as battery back up. Note:1.
