16-Bit Dual Supply Bus Transceiver
CMOS 16-bit dual supply voltage interface bus transceiver
fabricated with silicon gate CMOS technology.
or 2.5-V bus in mixed 5-V/3.3-V or 2.5-V supply systems, it achieves
high-speed operation while maintaining the CMOS low power
dissipation.
data busses. The direction of data transmission is determined by the
level of the DIR input. The enable input ( OE ) can be used to disable
the device so that the buses are effectively isolated. The B-port
interfaces with the 5-V bus, the A-port with the 3.3-V or 2.5-V bus.
Features (Note)
The TC74LCX164245FT is a dual supply, advanced high-speed
Designed for use as an interface between a 5-V bus and a 3.3-V
It is intended for 2 way asynchronous communication between
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Bidirectional interface between 5-V and 3.3-V or 2.5-V buses
High-speed: t
Low power dissipation: I
Symmetrical ouput impedance: I
Power-down protection provided on all inputs and outputs
Allows A port and V
Latch-up performance: −500 mA
Package: TSSOP
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 fixed by means of pull-up or pull-down resistors.
