The LCX162244 is a 16-bit buffer/line driver designed for low voltage (2.5V or 3.3V) VCC applications with the capability of interfacing to a 5V signal environment. The device supports 5V inputs and outputs, has 2.3V–3.6V VCC specifications, and outputs have a 26 Ohm (nominal) equivalent series resistance to reduce overshoot and undershoot and are designed to sink/source up to 12 mA at VCC 3.0V. The LCX162244 is fabricated using an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
The 74LCX162244 is an advanced CMOS device containing sixteen non-inverting buffers with 3-STATE outputs. It features equivalent 26Ω series resistors in the outputs to reduce overshoot and undershoot, making external termination unnecessary for many applications.
Designed for low voltage (2.5V or 3.3V) environments, the device can interface with a 5V signal environment. The outputs are capable of driving up to +12 mA at Vcc = 3.0V. The chip is nibble-controlled, allowing separate control inputs for each group of four bits.
| Output Drive Current | +12 mA (at Vcc = 3.0V) |
|---|---|
| Series Output Resistance | 26Ω nominal |
| Propagation Delay (Max) | 5.3 ns (at Vcc = 3.0V) |
| Operating Temperature | -40°C to +85°C |
The device has 5V tolerant inputs and outputs, allowing it to interface with a 5V signal environment while operating at lower voltages.
The device is nibble (4 bits) controlled, with each nibble having separate 3-STATE control inputs that can be shorted together for full 16-bit operation.
