Overview
TC74VHC245F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC245F, TC74VHC245FK Octal Bus Transceiver The TC74VHC245 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.
TC74VHC245F TC74VHC245FK Features (Note 1) (Note 2) (Note 3)  High speed: tpd = 4.
0 ns (typ.
) at VCC = 5 V  Low power dissipation: ICC = 4 µA (max) at Ta = 25°C  High noise immunity: VNIH = VNIL = 28% VCC (min)  Balanced propagation delays: tpLH ∼− tpHL  Wide operating voltage range: VCC (opr) = 2 V to 5.
5 V  Low noise: VOLP = 1.
0 V (max)  Pin and function compatible with 74ALS245 Weight SOP20-P-300-1.
27A VSSOP20-P-0030-0.

03 g (typ.
) Note 1: Do not apply a signal to any bus terminal when it is in the output mode.
Damage may result.
Note 2: All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull down resistors.
Note 3: A parasitic diode is formed between the bus and VCC terminals.
Therefore bus terminal can not be used to interface 5 V to 3 V systems directly.
