74ALVCH16600DGGY

Overview

The Nexperia 74ALVCH16600DGGY is an 18-bit universal bus transceiver with 3-state outputs, housed in a 56-lead TSSOP (SOT364-1) package. It operates within a supply voltage range of 1.65 V to 3.6 V and supports ambient temperatures from -40 °C to +85 °C. The device features independent control for A-to-B and B-to-A data flow via output enable, latch enable, clock enable, and clock inputs. Propagation delay ranges from 1.0 ns to 5.7 ns depending on voltage and direction. Output drive capability reaches ±24 mA at 3.0 V.

Feature Summary

• Supports partial power-down applications using IOFF circuitry to prevent damaging backflow current
• Features MULTIBYTE flow-through standard pin-out architecture with low inductance multiple VCC and GND pins
• Includes bus hold functionality on all data inputs

Applications

• High-speed data transfer between buses operating at different voltage levels
• Memory interface circuits requiring bidirectional data buffering
• System architectures utilizing mixed-voltage logic domains

Procurement Notes

Verify the specific ordering suffix 'Y' against the manufacturer's latest documentation to confirm tape-and-reel packaging specifications. Confirm that the DGG package variant matches the required footprint dimensions for the target PCB layout. Ensure design compliance with the specified absolute maximum ratings to avoid permanent device damage.

Selection Notes

Select this component when designing systems requiring 18-bit wide bidirectional data paths with flexible latching and clocking controls. The ALVCH series provides direct interface compatibility with TTL levels at higher supply voltages. Consider the low inductance pin configuration for applications sensitive to ground bounce and noise in high-speed switching environments.

Part Context

This device belongs to the Nexperia 74ALVCH family of advanced low-voltage CMOS logic products. It functions as a universal bus transceiver, combining the capabilities of a buffer and a latch. The 74ALVCH16600DGGY specifically denotes the version packaged in the thin shrink small outline plastic case SOT364-1.
