74VC March 1998 Revised October 2004 X16 500 74VCX16500 Lo Low Voltage 18-Bit Universal Bus Transceivers with w V 3.6V Tolerant Inputs and Outputs oltage General Description Features The VCX16500 is an 18-bit universal bus transceiver which s 1.4V to 3.6V VCC supply operation 1 combines D-type latches and D-type flip-flops to allow data s 3.6V tolerant inputs and outputs 8 flow in transparent, latched, and clocked modes. -Bi s t Data flow in each direction is controlled by output-enable PD (A to B, B to A) t (OEAB and OEBA), latch-enable (LEAB and LEBA), and 2.9 ns max for 3.0V to 3.6V VCC Univer clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the s Power-down high impedance inputs and outputs device operates in the transparent mode when LEAB is s Supports live insertion/withdrawal (Note 1) HIGH. When LEAB is LOW, the A data is latched if CLKAB s is held at a HIGH or LOW logic level. If LEAB is LOW, the A Static Drive (IOH/IOL) sal Bus T bus data is stored in the latch/flip-flop on the HIGH-to-LOW ±24 mA @ 3.0V VCC transition of CLKAB. When OEAB is HIGH, the outputs are s Uses patented noise/EMI reduction circuitry active. When OEAB is LOW, the outputs are in a high- s impedance state. Latchup performance exceeds 300 mA s Data flow for B to A is similar to that of A to B but uses ESD performance: Human body model > 2000V r OEBA, LEBA, and CLKBA. The output enables are com- ansce plementary (OEAB is active HIGH and OEBA is active Machine model >200V LOW).
