Low Voltage Octal Registered Transceiver with 5V Tolerant Inputs and Outputs
74LCX543 Low Voltage Octal Registered Transceiver with 5V Tolerant Inputs and Outputs May 1995 Revised March 2001 74LCX543 Low Voltage Octal Registered Transceiver with 5V Tolerant Inputs and Outputs General Description Features The LCX543 is a non-inverting octal transceiver containing5V tolerant inputs and outputs two sets of D-type registers for temporary storage of data2.3V − 3.6V V specifications provided CC flowing in either direction. Separate Latch Enable and Out- 7.0 ns t max (V = 3.3V), 10 μA I max PD CC CC put Enable inputs are provided for each register to permit independent input and output control in either direction ofPower down high impedance inputs and outputs data flow.Supports live insertion/withdrawal (Note 1) The LCX543 is designed for low voltage (2.5V or 3.3V) V CC±24 mA Output Drive (V = 3.0V) CC applications with capability of interfacing to a 5V signal Implements patented noise/EMI reduction circuitry environment. Latch-up performance exceeds 500 mA The LCX543 is fabricated with an advanced CMOS tech- ESD performance: nology to achieve high speed operation while maintaining Human body model > 2000V CMOS low power dissipation. Machine model > 200V Note 1: To ensure the high-impedance state during power up or down, OE should be tied to V through a pull-up resistor: the minimum value or the CC resistor is determined by the current-sourcing capability of the driver.
