1. Functional Description

•

Octal Bus Transceiver

2. General

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.

3. Features (Note)

(1) AEC-Q100 (Rev. H) (Note 1)

(2) Wide operating temperature range: Topr = -40 to 125 �

(3) High speed: Propagation delay time = 4.0 ns (typ.) at VCC = 5.0 V

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

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

(6) Balanced propagation delays: tPLH ≈ tPHL

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

(8) Low noise: VOLP = 1.0 V (max)

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

Note: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.

All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull down

resistors.

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.

Note 1: This device is compliant with the reliability requirements of AEC-Q100. For details, contact your Toshiba sales

representative.
