T3GE9WBG
Dual Supply Bus Transceiver for SD Card
The T3GE9WBG is a dual supply, advanced high-speed CMOS
dual supply voltage interface bus transceiver fabricated with
silicon gate CMOS technology.
Designed for use as an interface between a 1.8-V bus and a
2.9-V bus in mixed 1.8-V/2.9-V supply systems.
The A-port interfaces with the 1.8-V bus, the B-port with the
2.9-V bus.
The direction of data transmission is determined by the level of
the DIR input.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Weight: 0.006 g (typ.)
Features
Bidirectional interface between 1.8-V and 2.9-V buses.
