Description
Low-voltage 18-bit Universal Bus Driver With 3.6-v Tolerant Inputs And Outputs
Manufacturer
TOSHIBA Semiconductor CORPORATION
Datasheet
Low-Voltage 18-Bit Universal Bus Driver with 3.6-V Tolerant Inputs and Outputs
universal bus driver. 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.

stored in the latch/flip-flop on the low-to-high transition of CK.
overshoot and undershoot without external resistor.
Features
The TC74VCX162834FT is a high-performance CMOS 18-bit
It is also designed with overvoltage tolerant inputs and outputs
Data flow from A to Y is controlled by the output-enable (OE)
When LE is high, the A data is latched if the clock (CK) input
When OE is high, the outputs are in a high-impedance state. The 26-Ω series resistor helps reducing output
All inputs are equipped with protection circuits against static discharge.
