74ALVCH16600DGG512

Overview

The 74ALVCH16600DGG512 is an 18-bit universal bus transceiver with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 1.65 V to 3.6 V and supports data flow control via OEAB, LEAB, CEAB, CPAB, OEBA, LEBA, CEBA, and CPBA inputs. The device features bus hold inputs, IOFF circuitry for partial power down applications, and low inductance multiple VCC and GND pins. It complies with JEDEC standards JESD8-7, JESD8-5, and JESD8C, and provides ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Universal transceiver architecture with independent A-to-B and B-to-A data flow control.
• IOFF circuitry prevents damaging backflow current during partial power down states.
• Bus hold inputs eliminate the need for external pull-up or pull-down resistors.
• Low inductance multiple VCC and GND pins minimize noise and ground bounce.

Applications

• Partial power down systems requiring IOFF functionality.
• High-speed bidirectional bus interfaces operating at 2.5 V or 3.3 V.
• Systems requiring direct interface with TTL logic levels.

Procurement Notes

Verify the specific ordering suffix '512' against official Nexperia documentation, as the primary datasheet lists 'DGG' without this suffix. Confirm package type SOT364-1 (TSSOP56) matches design requirements. Ensure compliance with JEDEC standards and ESD ratings aligns with system specifications before procurement.

Selection Notes

Select this component for designs requiring 18-bit bidirectional data transfer with flexible latching and clocking controls. The wide supply voltage range accommodates 1.65 V to 3.6 V operation. Consider the TSSOP56 package constraints and thermal dissipation limits when integrating into high-density PCB layouts.

Part Context

This device belongs to the 74ALVCH series of CMOS logic ICs. It is part of a family of universal bus transceivers designed for low-power, high-speed applications. The product is manufactured by Nexperia, continuing the lineage of similar components previously produced by Philips Semiconductors.

Replacement Considerations

Consult official Nexperia documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when considering alternatives from other manufacturers.

FAQ

How does the IOFF feature function?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What is the purpose of the bus hold inputs?

Bus hold inputs maintain the last known state of the data lines, eliminating the need for external pull-up or pull-down resistors.
