TOSHIBA Digital Integrated Circuit Silicon Monolithic
TC7MP3245FTG
Low Voltage/Low Power 4-Bit × 2 Dual Supply Bus Transceiver
The TC7MP3245FTG is a dual supply, 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.
Features
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 : tpd = 6.8 ns (max) (VCCA = 2.5 ± 0.2 V, VCCB = 3.3 ± 0.3 V)
tpd = 8.9 ns (max) (VCCA = 1.8 ± 0.15 V, VCCB = 3.3 ± 0.3 V)
tpd = 10.3 ns (max) (VCCA = 1.5 ± 0.1 V, VCCB = 3.3 ± 0.3 V)
tpd = 61 ns (max) (VCCA = 1.2 ± 0.1 V, VCCB = 3.3 ± 0.3 V)
tpd = 9.5 ns (max) (VCCA = 1.8 ± 0.15 V, VCCB = 2.5 ± 0.2 V)
tpd = 10.8 ns (max) (VCCA = 1.5 ± 0.1 V, VCCB = 2.5 ± 0.2 V)
tpd = 60 ns (max) (VCCA = 1.2 ± 0.1 V, VCCB = 2.5 ± 0.2 V)
tpd = 58 ns (max) (VCCA = 1.2 ± 0.1 V, VCCB = 1.5 ± 0.1 V)
Output current : IOH/IOL = ±12 mA (min) (VCC = 3.0 V)
www.DataSheet4U.com
IOH/IOL = ±9 mA (min) (VCC = 2.3 V)
IOH/IOL = ±3 mA (min) (VCC = 1.65 V)
IOH/IOL = ±1 mA (min) (VCC = 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 pins when it is in the output mode. Damage may result.
Note 2: When mounting VQON package, the type of recommended flux is RA or RMA.
