TC7MPN3245FTG
Low Voltage/Low Power 4-Bit × 2 Dual Supply Bus Transceiver
The TC7MPN3245FTG is an advanced high-speed CMOS 8-bit
dual supply voltage interface bus transceiver, fabricated with silicon
gate CMOS technology.
It is also designed with over-voltage tolerant inputs and outputs up
to 3.6 V.
Designed for use as an interface between a 1.2-V, 1.5-V, 1.8-V, 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 A-port interfaces with the 1.2-V, 1.5-V, 1.8-V or 2.5-V bus, the
B-port with the 1.8-V, 2.5-V, 3.3-V bus.
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.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.

I_OHA/I_OLA = ±3 mA (min) (V_CCA = 1.65 V)
I_OHA/I_OLA = ±1 mA (min) (V_CCA = 1.4 V)
• Latch-up performance: ±300 mA
• ESD performance: Machine model ≥ ±200 V
Human body model ≥ ±2000 V
• Ultra-small package: VQON24
• Low current consumption : Using the new circuit significantly reduces current consumption when OE = “H”.
Suitable for battery-driven applications such as PDAs and cellular phones.
• Floating A-bus and B-bus are permitted. (when OE = “H”)
3.6-V tolerant function and power-down protection provided on all inputs and outputs.
Note 1: Do not apply a signal to any bus pin when it is in the output mode. Damage may result.
Note 2: RA or RMA flux is recommended when mounting the VQON package.
