The 74VHC245FT is an advanced high speed CMOS OCTAL BUS TRANSCEIVER fabricated with silicon gate C2MOS 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. All inputs are equipped with protection circuits against static discharge.

Wide operating temperature range: Topr = -40 to 125 

High speed: tpd = 3.9 ns (typ.) at VCC = 5 V

Low power dissipation: ICC = 4.0 μA (max) at Ta = 25 

High noise immunity: VNIH = VNIL = 28 % VCC (min)

Power down protection is provided on all inputs.

Balanced propagation delays: tPLH ≈ tPHL

Wide operating voltage range: VCC(opr) = 2.0 V to 5.5 V

Low noise: VOLP = 0.8 V (max)

Pin and function compatible with the 74 series (AC/HC/AHC/LV etc.) 245
