DESCRIPTION

· The 74ALVCH16600 is an 18-bit universal transceiver with bus hold inputs and 3-state outputs.

· Data flow in each direction is controlled by output enable, latch enable, clock enable, and clock inputs.

· For A-to-B data flow, the device operates in transparent mode when LEAB is HIGH; when LEAB is LOW, A data is latched if CPAB is held at a HIGH or LOW logic level.

· If LEAB and CEAB are LOW, A-bus data is stored in the latch/flip-flop on the HIGH-to-LOW transition of CPAB.

· When OEAB is HIGH, the outputs are active; when OEAB is LOW, the outputs are in the high-impedance state.

· B-to-A data flow is similar to A-to-B but uses OEBA, LEBA, CEBA, and CPBA.

· The device is fully specified for partial power-down applications using I OFF, which disables the output to prevent backflow current.

FEATURES

· Wide supply voltage range from 1.65 V to 3.6 V.

· CMOS low power dissipation.

· MULTIBYTE™ flow-through standard pin-out architecture.

· Low inductance multiple V CC and GND pins for minimum noise and ground bounce.

· Direct interface with TTL levels (2.7 V to 3.6 V).

· Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

· Bus hold on data inputs.

· Output drive capability 50 Ω transmission lines at 85 °C.

· Current drive ±24 mA at 3.0 V.

· Complies with JEDEC standards: JESD8-7, JESD8-5, JESD8C.

· ESD protection: HBM exceeds 2000 V, CDM exceeds 1000 V.

· Specified from -40 °C to +85 °C.
