DESCRIPTION

· The 74ALVCH16500 is an 18-bit universal transceiver with bus hold inputs and 3-state outputs.

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

· Operates in transparent mode when latch enable is HIGH; latches data on HIGH-to-LOW clock transition when latch enable is LOW.

· Outputs are active when output enable is HIGH; high-impedance state when output enable is LOW.

· Fully specified for partial power down applications using I OFF to prevent backflow current.

FEATURES

· Wide supply voltage range: 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).

· Bus hold on data inputs.

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

· 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/JESD36.

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

· Operating temperature range: -40 °C to +85 °C.

APPLICATIONS

· Suitable for partial power down applications.

· Ideal for systems requiring bus hold on data inputs.

· Used in environments with low inductance and ground bounce concerns.

· Compatible with TTL level interfaces.

· Designed for high-speed data transmission with robust ESD protection.
