1 / 9 page © 2001 Fairchild Semiconductor Corporation DS012464 www.fairchildsemi.com May 1995 Revised April 2001 74LCX16543 Low Voltage 16-Bit Registered Transceiver with 5V Tolerant Inputs and Outputs General Description The LCX16543 contains sixteen non-inverting transceivers containing two sets of D-type registers for temporary stor- age of data flowing in either direction. Each byte has sepa- rate control inputs which can be shorted together for full 16-bit operation. Separate Latch Enable and Output Enable inputs are provided for each register to permit inde- pendent input and output control in either direction of data flow. The LCX16543 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX16543 is fabricated with an advanced CMOS tech- nology to achieve high speed operation while maintaining CMOS low power dissipation. Features s 5V tolerant inputs and outputs s 2.3V–3.6V VCC specifications provided s 5.2 ns tPD max (VCC = 3.3V), 20 µA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s ±24 mA Output Drive (V CC = 3.0V) s Implements patented noise/EMI reduction circuitry s Latch-up performance exceeds 500 mA s ESD performance: Human Body Model > 2000V Machine Model > 200V Note 1: To ensure the high-impedance state during power up or down, OE should be tied to VCC through a pull-up resistor: the minimum value or the resistor is determined by the current-sourcing capability of the driver. Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
