EL5423CR

Instrumentation, Op Amps, Buffer Amps Overview

The EL5423CR is a 12-channel rail-to-rail input/output buffer manufactured by Renesas Electronics Corporation (formerly Intersil). It features a -3dB bandwidth of 12MHz and operates from supply voltages ranging from 4.5V to 16.5V. The device draws 600µA per buffer with a high slew rate of 15V/µs and continuous output drive capability of 30mA. It is housed in a 28-lead TSSOP package and specified for operation over the -40°C to +85°C temperature range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix to confirm package type and lead-free status. The 'CR' suffix indicates the 28-lead TSSOP package. Ensure compatibility with RoHS compliance requirements if Pb-Free Plus Anneal versions are needed. Confirm thermal management strategies for the TSSOP package under maximum load conditions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple buffered channels are required in a compact form factor. The 12-channel topology suits space-constrained designs needing high-speed buffering. Consider the 28-lead TSSOP package for surface-mount assembly. Evaluate thermal dissipation capabilities against expected load currents to ensure operation within safe junction temperatures.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the EL5x23 family of low-power, high-voltage rail-to-rail buffers. The family includes quad (EL5123), octal (EL5223), and 10-channel (EL5323) variants. All share identical electrical characteristics but differ in channel count and physical package dimensions to accommodate various integration needs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include other members of the EL5x23 family such as the EL5123, EL5223, or EL5323, provided the pinout and channel count match the design requirements. Verify package compatibility when swapping between different channel counts.
