Datasheet
Low-Voltage 18-Bit Universal Bus Transceiver with 3.6-V Tolerant Inputs and Outputs
universal 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.

(CKAB and CKBA) inputs. The clock can be controlled by the
clock-enable (CKENAB and CKENBA) inputs.
mode when LEAB is high. When LEAB is low, the A data is
latched if CKAB is held at a high or low logic level. If LEAB is low, the A-bus data is stored in the latch/flip-flop on
the high-to-low transition of CKAB.
3-state memory address drivers, etc.
Features (Note)
The TC74VCX16600FT is a high performance CMOS 18-bit
It is also designed with overvoltage tolerant inputs and outputs
Data flow in each direction is controlled by output-enable
For A-to-B data flow, the device operates in the transparent
Data flow for B to A is similar to that of A to B but uses OEBA, LEBA, CKBA, and CKENBA.
When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with
All inputs are equipped with protection circuits against static discharge.
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
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.
