1. Functional Description ? Low-Voltage 16-Bit Bus Transceiver with 3.6-V Tolerant Inputs and Outputs

2. General

The TC74VCX16245 is a high-performance CMOS 16-bit bus transceiver. Designed for use in 1.8 V, 2.5 V or 3.3

V systems, it achieves high-speed operation while maintaining the CMOS low power dissipation.

It is also designed with overvoltage tolerant inputs and outputs up to 3.6 V.

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 transceivers 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.

All inputs are equipped with protection circuits against static discharge.

3. Features (Note)

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

? (Note 1)

(2) Low-voltage operation: VCC = 1.8 to 3.6 V

(3) High-speed operation: tpd = 2.5 ns (max) (VCC = 3.0 to 3.6 V)

tpd = 3.0 ns (max) (VCC = 2.3 to 2.7 V)

tpd = 5.0 ns (max) (VCC = 1.8 V)

(4) Output current: IOH/IOL =

±24 mA (min) (VCC = 3.0 V)

IOH/IOL =

±18 mA (min) (VCC = 2.3 V)

IOH/IOL =

±6 mA (min) (VCC = 1.8 V)

(5) Bidirectional interface between 2.5 V and 3.3 V signals

(6) 3.6 V tolerant function and 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 levels fixed by means of pull-up or pull-down

resistors.
