Low Voltage Octal Registered Transceiver

74LCX543 Low Voltage Octal Registered Transceiver with 5V Tolerant Inputs and Outputs May 1995 Revised April 1999 74LCX543 Low Voltage Octal Registered Transceiver with 5V Tolerant Inputs and Outputs General Description The LCX543 is a non-inverting octal transceiver containing two sets of D-type registers for temporary storage of data flowing in either direction. Separate Latch Enable and Output Enable inputs are provided for each register to permit independent input and output control in either direction of data flow. The LCX543 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX543 is fabricated with an advanced CMOS technology 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 7.0 ns tPD max (VCC = 3.3V), 10 µA ICC max s Power down high impedance inputs and outputs s Supports live insertion/withdrawal (Note 1) s ±24 mA Output Drive (VCC = 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.
