Low-Voltage Octal Bus Transceiver with 5-V Tolerant Inputs and Outputs

The TC74LCX245 is a high-performance CMOS octal bus

transceiver. Designed for use in 3.3-V systems, it achieves

high-speed operation while maintaining the CMOS low power

dissipation.

The device is designed for low-voltage (3.3 V) VCC applications,

but it could be used to interface to 5-V supply environment for

both inputs and outputs.

The direction of data transmission is determined by the level of

the DIR input. The enable input ( OE ) can be used to disable the

device so that the busses are effectively isolated.

All inputs are equipped with protection circuits against static

discharge.

Features (Note)

•

Low-voltage operation: V

= 1.65 to 3.6 V

High-speed operation: t = 7.0 ns (max) (V

= 3.0 to 3.6 V)

Ouput current: |I |/I

= 24 mA (min) (V

= 3.0 V)

OH OL

Latch-up performance: ＞±500 mA

Available in JEITA SOP, TSSOP and VSSOP (US)

Bidirectional interface between 5.0 V and 3.3 V signals

Power-down protection provided on all inputs and outputs

Pin and function compatible with the 74 series

(74AC/VHC/HC/F/ALS/LS 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.

Weight

SOP20-P-300-1.27A
