74VHC245

Octal Bidirectional Transceiver with 3-STATE Outputs

The VHC245 is an advanced high speed CMOS octal bus transceiver fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The VHC245 is intended for bidirectional asynchronous communication between data busses. The direction of data transmission is determined by the level of the T/R# input. The enable input can be used to disable the device so that the busses are effectively isolated. All inputs are equipped with protection circuits against static discharge.

Features

  • High Speed: tPD = 4.0 ns (typ) at VCC = 5V
  • High Noise Immunity: VNIH = VNIL = 28% VCC (Min)
  • Power Down Protection is provided on all inputs
  • Low Noise: VOLP = 0.9V (typ)
  • Low Power Dissipation: ICC = 4 µA (Max) @ TA = 25°C
  • Pin and Function Compatible with 74HC245
