Low–Voltage 1.8/2.5/3.3V 16–Bit Buffer

With 3.6V-Tolerant Inputs and Outputs (3-State, Non-Inverting)

The MC74VCX16244 is an advanced performance, non–inverting 16–bit buffer. It is designed for very high–speed, very low–power operation in 1.8V, 2.5V or 3.3V systems.

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.

• 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

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
