74LCX16500 - Fairchild Semiconductor

74LCX16500 Low Voltage 18-Bit Universal Bus Transceivers

These 18-bit universal bus transceivers combine 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 LCX16500 is designed for low voltage (2.5V or 3.3V) VCC applicatio.

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 (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 determined by the current-sour.
