DESCRIPTION

· The 74ALVCH16501 is an 18-bit universal transceiver with bus hold inputs and 3-state outputs.

· Data flow in each direction is controlled by output enable (OEAB and OEBA), latch enable (LEAB and LEBA), and clock (CPAB and CPBA) inputs.

· The device operates in transparent mode when LEAB is HIGH and latches data on the LOW-to-HIGH transition of CPAB when LEAB is LOW.

· Outputs are active when OEAB is HIGH and in high-impedance state when OEAB is LOW.

· The device is fully specified for partial power down applications using IOFF.

FEATURES

· Wide supply voltage range from 1.2 V to 3.6 V.

· CMOS low power dissipation.

· Direct interface with TTL levels.

· Current drive ±24 mA at VCC = 3.0 V.

· Universal bus transceiver with D-type latches and D-type flip-flops capable of operating in transparent, latched or clocked mode.

· Bus hold on all data inputs.

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

· 3-state non-inverting outputs for bus-oriented applications.

· Latch-up performance exceeds 100 mA per JESD78 Class II.A.

· Complies with JEDEC standards: JESD8-7, JESD8-5, JESD8C/JESD36.

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

· Specified from -40 °C to +85 °C.

APPLICATIONS

· Suitable for bus-oriented applications requiring 3-state non-inverting outputs.

· Ideal for systems with wide supply voltage range and low power dissipation.

· Used in environments requiring direct interface with TTL levels.

· Applicable in systems needing bus hold on all data inputs.

· Suitable for high-speed data transmission with 50 Ω transmission lines.

· Used in systems requiring robust ESD protection and high latch-up performance.
