74LCX16652 Low Voltage Transceiver/Register with 5V Tolerant Inputs and Outputs February 1994 Revised April 1999 74LCX16652 Low Voltage Transceiver/Register with 5V Tolerant Inputs and Outputs General Description The LCX16652 contains sixteen non-inverting bidirectional bus transceivers with 3-STATE outputs providing multiplexed transmission of data directly from the input bus or from the 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 (see Functional Description). The LCX16652 is designed for low-voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX16652 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 5.7 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 (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 and OE tied to GND through a resistor: the minimum value or the resistor is determin...
