It is designed for very high–speed, very low–power operation in 1.8V, 2.5V or 3.3V systems. LOW–VOLTAGE 1.8/2.5/3.3V 16–BIT TRANSCEIVER When operating at 2.5V (or 1.8V) the part is designed to tolerate voltages it may encounter on either inputs or outputs when interfacing to 3.3V busses. It is guaranteed to be over–voltage tolerant to 3.6V. The VCX16245 is designed with byte control. It can be operated as two separate octals, or with the controls tied together, as a 16–bit wide function. The Transmit/Receive (T/Rn) inputs determine the direction of data flow through the bi–directional transceiver. Transmit (active–HIGH) enables data from A ports to B ports; Receive (active–LOW) enables data from B to A ports. The Output Enable inputs (OEn), when HIGH, disable both A and B ports by placing them in a HIGH Z condition. • Designed for Low Voltage Operation: VCC = 1.8–3.6V • 3.6V Tolerant Inputs and Outputs • High Speed Operation: 2.5ns max for 3.0 to 3.6V DT SUFFIX 48–LEAD PLASTIC TSSOP PACKAGE CASE 1201–01 3.2ns max for 2.3 to 2.7V 5.7ns max for 1.8V • Static Drive: • • • ±24mA Drive at 3.0V ±18mA Drive at 2.3V ±6mA Drive at 1.8V Supports Live Insertion and Withdrawal IOFF Specification Guarantees High Impedance When VCC = 0V Near Zero Static Supply Current in All Three Logic States (20µA) Substantially Reduces System Power Requirements • Latchup Performance Exceeds ±300mA • ESD Performance: Human Body Model >2000V; Machine Model >200V PIN NAMES Pins Function OEn T/Rn A0–A15 B0–B15 Output Enable Inputs Transmit/Receive Inputs Side A Inputs or 3–State Outputs Side B Inputs or 3–State Outputs This document contains information on a new product.
