TC74VCX16245FT
Low-Voltage 16-Bit Bus Transceiver with 3.6-V Tolerant Inputs and Outputs
The TC74VCX16245FT 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.
Weight: 0.25 g (typ.)
Features (Note)
•
Low-voltage operation: VCC = 1.8 to 3.6 V
•
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)
•
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)
•
Latch-up performance: −300 mA
•
ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 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.

Note 1: Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or
even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
