The document describes a low voltage 16-bit transparent latch from Fairchild Semiconductor Corporation, which has 5V tolerant inputs and outputs and a 26Ω series resistor. The product is designed for bus oriented applications and has byte control functionality. The flip-flops are transparent to the data when the Latch Enable (LE) is high. When LE is low, the data that meets the setup time is latched. Data appears on the bus when the Output Enable (OE) is low. When OE is high, the outputs are in a high impedance state. The product is designed for low voltage (2.5V or 3.3V) VCC applications with the capability of interfacing to a 5V signal environment. The 26Ω series resistor in the output helps reduce output overshoot and undershoot. The product is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.
