EL7232CS

Overview

The EL7232CS is a dual-channel, high-speed line driver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 16V and delivers a peak output current of 2A. The device features low quiescent current consumption of 2.5mA and supports clocking speeds up to 10MHz. Key timing parameters include a switching delay time of 20ns, with rise and fall times specified at 10ns and 13ns respectively. It utilizes an SOIC-8 surface-mount package and functions as a low-side FET driver with 3-state output capability.

Feature Summary

• Features 3-state output functionality for enhanced bus control
• Compatible with both 3V and 5V input logic levels
• Provides low, matched output impedance of 5Ω
• Designed for low quiescent power dissipation

Applications

• Parallel bus line drivers
• EPROM and PROM programming circuits
• Motor controls and charge pumps
• Sampling circuits and pin drivers
• Bridge circuits

Procurement Notes

Verify component authenticity through authorized channels due to the manufacturer's discontinuation status. Confirm RoHS compliance and moisture sensitivity level requirements before integration. Ensure the specific suffix matches the required packaging format. Validate that the obsolete status does not conflict with long-term support obligations for the target application.

Selection Notes

Select this component for applications requiring high-speed driving of capacitive lines with minimal clock skew. The matched rise and fall delays are critical for maintaining pulse-width integrity in microprocessor-based systems. Consider the 4.5V minimum supply voltage constraint when designing power rails. Evaluate the 2A peak drive capability against the load capacitance requirements of the target transmission lines.

Part Context

The EL7232 belongs to the EL7232 series of dual channel drivers. It serves as a replacement for industry standard DS0026 clock drivers, offering improved response times and reduced supply currents compared to bipolar alternatives. The device is part of Renesas' portfolio of power management ICs, specifically categorized under gate drivers and half-bridge drivers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The EL7232CNZ is listed as an obsolete PDIP variant within the same family. Designers should verify compatibility with alternative high-speed line drivers if the EL7232CS is unavailable.
