GeneralGeneralGeneralGeneral The 74VHCV245FT is an advanced high speed CMOS OCTAL BUS TRANSCEIVER fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It is intended for two-way asynchronous communication between data busses. The direction of data transmission is determined by the level of the DIR input. The enable input (G) can be used to disable the device so that the busses are effectively isolated. Input pin and bus terminal have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHCV245FT is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, etc. Note: Output in off-state. 3. 3. Features (Note)Features (Note) 3. 3.

(8) Pin and function compatible with the 74 series (74AC/HC/AHC/LV etc.) 245 type. Note: Do not apply a signal to any bus pins when it is in the output mode. Damage may result. All floating (high impedance) bus pins must have their input levels fixed by means of pull-up or pull-down resistors. Note 1: This device is compliant with the reliability requirements of AEC-Q100.
