Features (Note)
Note:
All floating (high impedance) bus pins must have their input level fixed by means of pull-up or pull-down resistors.
The TC74VCX16646FT is a high-performance CMOS 16-bit bus
It is also designed with overvoltage tolerant inputs and outputs
This device is bus transceiver with 3-state outputs, D-type
All inputs are equipped with protection circuits against static
Low-voltage operation: V
High-speed operation: t
Output current : I
Latch-up performance: −300 mA
ESD performance: Machine model ≥ ±200 V
Package: TSSOP
Bidirectional interface between 2.5 V and 3.3 V signals.
3.6-V tolerant function and power-down protection provided on all inputs and outputs
Do not apply a signal to any bus pins when it is in the output mode. Damage may result.
