TC7SP3125CFC集成電路（IC）的轉換器電平移位器規(guī)格書PDF中文資料

The TC7SP3125 is an advanced high-speed CMOS 1-bit dual

supply voltage interface bus buffer 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 3.3-V bus in mixed 1.2-V, 1.5-V,

1.8-V or 2.5-V/1.8-V, 2.5-V or 3.3-V supply systems.

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

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

The enable input (OE ) can be used to disable the device so

that the signal lines are effectively isolated.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.

Features (Note)

? Level converter for interfacing 1.2-V to 1.8-V, 1.2-V to 2.5-V, 1.2-V to 3.3-V, 1.5-V to 2.5-V, 1.5-V to 3.3-V, 1.8-V

to 2.5-V, 1.8-V to 3.3-V or 2.5 V to 3.3-V system.

tpd = 7.8 ns (max) (VCCA = 1.8 ± 0.15 V, VCCB = 3.3 ± 0.3 V)

tpd = 8.6 ns (max) (VCCA = 1.5 ± 0.1 V, VCCB = 3.3 ± 0.3 V)

tpd = 22 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 = 10.5 ns (max) (VCCA = 1.5 ± 0.1 V, VCCB = 2.5 ± 0.2 V)

tpd = 23 ns (max) (VCCA = 1.2 ± 0.1 V, VCCB = 2.5 ± 0.2 V)

tpd = 30 ns (max) (VCCA = 1.2 ± 0.1 V, VCCB = 1.8 ± 0.15 V)

? Output current : IOHB / IOLB = ±12 mA (min) (VCCB = 3.0 V)

IOHB / IOLB = ±9mA (min) (VCCB = 2.3 V)

IOHB / IOLB = ±3 mA (min) (VCCB = 1.65 V)

? Latch-up performance: -300 mA

? ESD performance: Machine model ≥ ±200 V

Human body model ≥ ±2000 V

? Ultra-small package: CSON6(CST6C)

? 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 is permitted. (when OE = “H”)

? 3.6-V tolerant function and power-down protection provided on all inputs and outputs.

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