PI74ALVTC16245 Datasheet | Pericom Semiconductor

Features - PI74ALVTC family is designed for low voltage operation, VDD = 1.8V to 3.6V - Supports Live Insertion - 3.6V I/O Tolerant Inputs and Outputs - Bus Hold .. - High Drive, Description Peri Semiconductor’s PI74ALVTC16245 is a 16-bit bidirectional transceiver designed for asynchronous two-way munication between data buses. The direction control input pin (x DIR) determines the direction of data flow through the bidirectional transceiver. The Direction and Output Enable controls are designed to operate this device as either two independent 8-bit transceivers or one 16-bit transceiver. The output enable (OE) input, when HIGH, disables both A and B ports by placing them in Hi-Z condition. To ensure the high-impedance state during power up or power down, OE should be tied to Vdd through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The family offers both I/O Tolerant, which allows it to operate in mixed 1.8/3.6V systems, and “Bus Hold,” which retains the data input’s last state whenever the data input goes to high-impedance, preventing “floating” inputs and eliminating the need for pullup/ down resistors. -32/64m A @ 3.3V - Uses patented noise reduction circuitry - Power-off high impedance inputs and outputs - Industrial operation at - 40°C to +85°C - Packaging (Pb-free & Green available): - 48-pin 240- mil wide plastic TSSOP (A) - 48-pin 173-mil wide plastic TVSOP (K) - 48-pin 300-mil wide plastic SSOP (V) Block Diagram 1DIR 1OE 1A0 1B0 1A1 1B1 1A2 1B2 1A3 1B3 1A4 1B4 1A5 2A6 2A5 2B4 2 A4 2B3 2A3 2B2 2A1 2B1 2DIR 2OE 2A0 2B0 1B5 1A6 1B6 1A7 1B7 2A8 2A7 2B5 2B6 2B7 PS8354B 09/22/04 PI74ALVTC16245 16-Bit Bi Directional Transceiver with 3-State Outputs 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012...
