Low Voltage Octal Transparent Latch with 5V Tolerant Inputs and Outputs
| | |  |  |  |
|
|
General Description
|
The LCX373 consists of eight latches with 3-STATE outputs for bus organized system applications. The device is designed for low voltage (3.3V or 2.5V) VCC applications with capability of interfacing to a 5V signal environment.
The LCX373 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
