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
Weight: 0.03 g (typ.)
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.

• Output current : IOHB/IOLB = ±3 mA (min) (VCCB = 3.0 V) IOHB/IOLB = ±2 mA (min) (VCCB = 2.3 V) IOHB/IOLB = ±0.5 mA (min) (VCCB = 1.65 V) IOHA/IOLA = ±9 mA (min) (VCCA = 2.3 V) IOHA/IOLA = ±3 mA (min) (VCCA = 1.65 V) IOHA/IOLA = ±1 mA (min) (VCCA = 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.

Note 1:
Exceeding any of the absolute maximum ratings, even briefly, may 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).
Note 2: Do not supply a voltage to V.
