TC74VCX16834FT
Low-Voltage 18-Bit Universal Bus Driver with 3.6-V Tolerant Inputs and Outputs
The TC74VCX16834FT is a high-performance CMOS 18-bit
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.
It is also designed with overvoltage tolerant inputs and outputs
up to 3.6 V.
Data flow from A to Y is controlled by the output-enable (OE)
input. The device operates in the transparent mode when the
latch-enable (LE) input is low.
When LE is high, the A data is latched if the clock (CK) input
is held at a high or low logic level. If LE is high, the A data is
Weight: 0.25 g (typ.)
stored in the latch/flip-flop on the low-to-high transition of CK.
When OE is high, the outputs are in the high-impedance state.
All inputs are equipped with protection circuits against static discharge.
