TC74LCX16245FT

Low-Voltage 16-Bit Bus Transceiver with 5-V Tolerant Inputs and Outputs

The TC74LCX16245FT is a high-performance CMOS 16-bit bus

transceiver. Designed for use in 2.5-V or 3.3-V systems, it

achieves high-speed operation while maintaining the CMOS low

power dissipation.

The device is designed for low-voltage (2.5-V or 3.3-V) V

applications, but it could be used to interface to 5-V supply

environment for both inputs and outputs.

This 16-bit bus transceiver is controlled by direction control

(DIR) inputs and output enable ( OE ) inputs which are common

to each byte. It can be used as two 8-bit transceiver or one 16-bit

transceiver. The direction of data transmission is determined by

the level of the DIR inputs. The OE inputs can be used to

disable the device so that the busses are effectively isolated.

Weight: 0.25 g (typ.)

All inputs are equipped with protection circuits against static discharge.

Features (Note)

•

Low-voltage operation: V

= 2.0 to 3.6 V

High-speed operation: t = 4.5 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

Package: TSSOP

Bidirectional interface between 5.0 V and low-voltage (2.5-V or 3.3-V) signals

Power-down protection provided on all inputs and outputs

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 level fixed by means of pull-up or pull-down

resistors.
