1 / 8 page © 2001 Fairchild Semiconductor Corporation DS012550 www.fairchildsemi.com October 1995 Revised March 2001 74LCX16501 Low Voltage 18-Bit Universal Bus Transceivers with 5V Tolerant Inputs and Outputs General Description The LCX16501 is an 18-bit universal bus transceiver com- bining D-type latches and D-type flip-flops to allow data flow in transparent, latched, and clocked modes. Data flow in each direction is controlled by output-enable (OEAB and OEBA), latch-enable (LEAB and LEBA), and clock (CLKAB and CLKBA) inputs. The LCX16501 is designed for low voltage (2.5V or 3.3V) VCC applications with capability of interfacing to a 5V signal environment. The LCX16501 is fabricated with an advanced CMOS tech- nology to achieve high speed operation while maintaining CMOS low power. Features s 5V tolerant inputs and outputs s 2.3V–3.6V VCC specifications provided s 6.0 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 and OE tied to GND through a resistor: the minimum value or the resistor is determined by the current-sourcing capability of the driver. Ordering Code: Devices also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
