Low Voltage/Low Power 4-Bit × 2 Dual Supply Bus Transceiver with Bushold

CMOS 8-bit dual supply voltage interface bus transceiver

fabricated with silicon gate CMOS technology.

or 2.5-V bus and a 1.8-V, 2.5-V or 3.6-V bus in mixed 1.2-V, 1.5-V,

1.8-V or 2.5-V/1.8-V, 2.5-V or 3.6-V supply systems.

the B-port with the 1.8-V, 2.5-V, 3.3-V bus.

the DIR input. The enable input ( OE ) can be used to disable the

device so that the buses are effectively isolated. The bus of a B

bus side at floating state is maintained in an appropriate logic

level due to a bushold circuit to a B bus. Moreover, the bushold circuit which is added to a B bus is off when OE is

low.

Features

•

The TC7MP3245FTG is a dual supply, advanced high-speed

Designed for use as an interface between a 1.2-V, 1.5-V, 1.8-V,

The A-port interfaces with the 1.2-V, 1.5-V, 1.8-V or 2.5-V bus,

The direction of data transmission is determined by the level of

All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Bidirectional interface between 1.2-V and 1.8-V, 1.2-V and 2.5-V, 1.2-V and 3.3-V, 1.5-V and 2.5-V, 1.5-V and

3.3-V, 1.8-V and 2.5-V, 1.8-V and 3.3-V or 2.5-V and 3.3-V buses.

High-speed operation : t

Output current : I

Latch-up performance: ±300 mA

ESD performance: Machine model ≥ ±200 V

Ultra-small package: VQON24

Bushold circuit is build in only the B bus side. (Only in OE = “H”, a former state is maintained.)

Low current consumption : Using the new circuit significantly reduces current consumption when OE = “H”.

Floating A-bus and B-bus are permitted. (when OE = “H”)

3.6-V tolerant function provided on A-bus terminal, DIR and OE terminal.

Note 1: Do not apply a signal to any bus pins when it is in the output mode. Damage may result.

Note: When mounting VQON package, the type of recommended flux is RA or RMA.
