IDT72V71623BCG8

Description

Multiplexer IC with 1 input and 16 outputs (1 x 1:16). It comes in a compact 144-ball ceramic ball grid array (144-CABGA) package measuring 13mm by 13mm. Designed for signal routing, this device allows one signal line to be switched to one of sixteen outputs. Operates with a single supply voltage range of 3V to 3.6V. The product operates over a temperature range from -40°C to 85°C. It is a surface-mount device suitable for high-density circuit board assemblies. This product is now obsolete but is offered as new, original stock with inventory available.

Device Structure

The device uses a multiplexing logic circuit to select one of sixteen output lines from a single input line based on control signals. The integrated circuit is housed in a ceramic ball grid array package offering improved thermal dissipation and mechanical stability during surface mounting.

Performance Characteristics

Switching speed, power consumption, and signal integrity values are optimized for low-voltage logic operations.

Supports operation in industrial temperature ranges (-40°C to 85°C).

Single supply operation simplifies power design.

The ceramic package enhances durability and reliability in harsh environments.

Application Environments

Signal routing and switching in communication equipment

Data multiplexing in telecommunications and networking hardware

Industrial control systems requiring rugged temperature performance

High-density printed circuit boards (PCBs) where space-saving is critical

Legacy systems using 3.3V logic levels

Selection Guidelines

Choose this multiplexer when a 1-to-16 channel selection is required on a single supply voltage of approximately 3.3V.

Suitable for applications with moderate to high-density surface mount technology (SMT) needs.

Consider the device’s obsolete status; verify long-term availability if designing new systems.

Ensure system operation within the -40°C to 85°C temperature range.

Select for applications demanding high reliability ceramic package format.

Usage Considerations

The package requires precise soldering conditions aligned with MSL 3 guidelines to avoid moisture damage.

Evaluate whether 1-to-16 multiplexing in a ceramic BGA package matches the system's physical and electrical constraints.

Since output current specifications are not explicitly provided, assess load driving capabilities against system requirements.

Since the product is obsolete, plan stock use accordingly and seek alternatives for new designs.

Potential Equivalent/Replacement Models

There may be alternative multiplexers from Renesas or other manufacturers with similar 1-to-16 configuration and 3.3V operation. For example, comparable devices in Renesas’s current 72V series or multiplexers from Texas Instruments, Analog Devices, or NXP offering similar channel counts and voltage ranges.

Equivalents may differ in package type (e.g., plastic BGA or QFN) and electrical specs; verify pin compatibility and performance before substitution.

No direct guaranteed drop-in replacement model is provided in the available data.
