Product Change Notification
The MC74VHC245 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 CMOS low power dissipation.

It is intended for two-way asynchronous communication between data buses. The direction of data transmission is determined by the level of the DIR input. The output enable pin (OE) can be used to disable the device, so that the buses are effectively isolated.

All inputs are equipped with protection circuits against static discharge.
Features
 
  • High Speed: tPD = 4.0ns (Typ) at VCC = 5V
  • Low Power Dissipation: ICC = 4µA (Max) at TA = 25 C
  • High Noise Immunity: VNIH = VNIL = 28% VCC
  • Power Down Protection Provided on Inputs
  • Balanced Propagation Delays
  • Designed for 2V to 5.5V Operating Range
  • Low Noise: VOLP = 1.2V (Max)
  • Pin and Function Compatible with Other Standard Logic Families
  • Latchup Performance Exceeds 300mA
  • ESD Performance: HBM > 2000V; Machine Model > 200V
  • Chip Complexity: 308 FETs or 77 Equivalent Gates

    APPLICATION NOTES
  • Do not force a signal on an I/O pin when it is an active output,
    damage may occur.
  • All floating (high impedance) input or I/O pins must be fixed by
    means of pull up or pull down resistors or bus terminator ICs.
  • A parasitic diode is formed between the bus and VCC terminals.
    Therefore, the VHC245 cannot be used to interface 5V to 3V systems
    directly.
  • These devices are available in Pb-free package(s). Specifications herein apply to both standard and Pb-free devices. Please see our website at www.onsemi.com for specific Pb-free orderable part numbers, or contact your local ON Semiconductor sales office or representative.
