Description and Introduction
Low Voltage 20-Bit Selectable Register/Buffer with 3.6V Tolerant Inputs and Outputs The 74VCX16839MTD is a low-voltage 20-bit universal bus driver manufactured by Fairchild Semiconductor (now part of ON Semiconductor). It operates at a voltage range of 1.2V to 3.6V, making it suitable for low-power and battery-operated applications. The device features 20 non-inverting buffers with 3-state outputs, allowing for bidirectional data flow. It supports partial power-down mode operation and has a typical propagation delay of 2.5 ns at 3.3V. The 74VCX16839MTD is designed with a TSSOP (Thin Shrink Small Outline Package) package and is RoHS compliant. It is commonly used in applications requiring high-speed data transfer and low power consumption.

Description and Introduction
Low Voltage 20-Bit Selectable Register/Buffer with 3.6V Tolerant Inputs and Outputs The 74VCX16839MTD is a low-voltage CMOS 20-bit universal bus driver manufactured by Fairchild Semiconductor. It operates with a supply voltage range of 1.2V to 3.6V, making it suitable for low-power applications. The device features 20 non-inverting buffers with 3-state outputs, which can be controlled by two output enable (OE) inputs. It supports partial power-down mode operation using IOFF circuitry to disable the outputs, preventing damaging current backflow when the device is powered down. The 74VCX16839MTD is designed with a 5V tolerant input/output capability, allowing it to interface with 5V logic levels. It is available in a TSSOP-56 package and is characterized for operation from -40°C to +85°C. The device is RoHS compliant and adheres to industry-standard specifications for low-voltage logic devices.
