74LCX652 Low Voltage Transceiver/Register with 5V Tolerant Inputs and Outputs February 1994 Revised April 1999 74LCX652 Low Voltage Transceiver/Register with 5V Tolerant Inputs and Outputs General Description The LCX652 consists of bus transceiver circuits with Dtype flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to the HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the transceiver function. The LCX652 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX652 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 drive...
