DESCRIPTION

· The 74ALVT16373 is a 16-bit D-type transparent latch with 3-state outputs.

· It can function as two 8-bit transparent latches or a single 16-bit transparent latch.

· Features two latch enables (1LE and 2LE) and two output enables (1OE and 2OE), each controlling 8 bits.

· When nLE is HIGH, data at the inputs enter the latches, making them transparent.

· When nLE is LOW, the latches store the information present at the inputs before the HIGH-to-LOW transition.

· A HIGH on nOE causes the outputs to assume a high-impedance OFF-state without affecting the latches.

· Bus hold data inputs eliminate the need for external pull-up resistors for unused inputs.

FEATURES

· Wide supply voltage range from 2.3 to 3.6 V.

· Overvoltage tolerant inputs up to 5.5 V.

· BiCMOS technology for high speed and output drive.

· 16-bit transparent latch with 3-state buffers.

· 5 V I/O compatibility.

· Output capability: +64 mA/–32 mA.

· Direct interface with TTL levels.

· Input and output interface capability to systems at 5 V supply.

· Bus-hold data inputs eliminate external pull-up resistors.

· Live insertion/extraction permitted.

· Power-up reset and 3-State functionality.

· No bus current loading when output is tied to 5 V bus.

· IOFF circuitry for partial Power-down mode operation.

· Latch-up performance exceeds 500 mA per JESD 78 Class II Level B.

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

· Specified temperature range: -40 °C to 85 °C.

APPLICATIONS

· Suitable for applications requiring 16-bit transparent latching with 3-state outputs.

· Ideal for systems with a wide supply voltage range and overvoltage tolerance.

· Useful in high-speed data transfer and output drive scenarios.

· Compatible with 5 V I/O systems and TTL level interfaces.

· Effective in systems where bus-hold data inputs are necessary to eliminate external pull-up resistors.

· Suitable for live insertion/extraction and power-up reset scenarios.

· Ideal for applications requiring ESD protection and latch-up performance.
