PI3VT3245 8-Bit, 2-Port, Low Voltage Translator Bus Switch Features - - - - - Near-Zero propagation delay Low On-Resistance switches connect inputs to outputs 2.5V to 3.3V Supply voltage operation 2.5V or 1.8V switching Packaging (Pb-free & Green available): - 20-pin, 150-mil wide plastic QSOP (Q) - 20-pin, 173-mil wide plastic TSSOP (L) Description Peri Semiconductor’s PI3VT series of logic circuits are produced using the pany’s advanced submicron CMOS technology, achieving industry leading performance. The PI3VT3245 is a 2.5V or 3.3V 8-bit, 2-port bus switch designed with a low On-Resistance (5Ω). The switches are turned ON or enabled by the Bus Enable (BE) input signal. Given a 3.3V supply and an input voltage of 3.3V, the switch translates to an output voltage of 2.5V. Similarly, when operated with a 2.5V supply and given 2.5V inputs, the device translates the outputs to 1.8V. Applications - 3.3V to 2.5V level shifting (voltage translation) - 2.5V to 1.8V level shifting (voltage translation) Block Diagram Pin Configuration NC 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 VCC BE B0 B1 B2 B3 B4 B5 B6 B7 A0 B0 A0 A1 A2 A7 B7 A3 A4 A5 A6 A7 GND Truth Table(1) Function Disconnect Connect Notes: 1.
