MC10EL12DT

Gates And Inverters - Multi-Function, Configurable Overview

The MC10EL12DT is a low impedance drive buffer from the onsemi 10EL series, functionally equivalent to the E112 device but with significantly faster propagation delays. It features two pairs of OR/NOR outputs designed for high drive applications such as memory addressing. The device operates in PECL mode (VCC = 4.2 V to 5.7 V, VEE = 0 V) and NECL mode (VCC = 0 V, VEE = −4.2 V to −5.7 V). Key electrical parameters include a typical propagation delay of 290 ps at 25°C, a maximum toggle frequency exceeding 3 GHz, and a power supply current of 17 mA. It includes internal input pulldown resistors and meets JEDEC latchup specifications.

Gates And Inverters - Multi-Function, Configurable Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the TSSOP-8 package when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation, as non-compliant variants may exist. Check for active production status or obsolescence notices before finalizing procurement plans to ensure long-term availability.

Gates And Inverters - Multi-Function, Configurable Selection Notes

Select this component for designs requiring fast switching speeds and strong output drive capabilities. Ensure the power supply configuration matches either PECL or NECL requirements. Consider the TSSOP-8 package constraints regarding thermal management and board space. Verify that the input voltage levels align with the specified VIH and VIL thresholds for reliable operation.

This part belongs to the MC10EL/100EL family of 5.0 V ECL low impedance drivers. The 'MC10' prefix denotes standard commercial grade performance, while 'MC100' indicates temperature-compensated versions. The 'DT' suffix specifically identifies the plastic TSSOP-8 surface-mount package variant within this product line.

Gates And Inverters - Multi-Function, Configurable Replacement Considerations

The MC10EL12 is functionally equivalent to the E112 device. Designers should verify pinout compatibility and electrical characteristics when substituting with other ECL buffers or drivers from different manufacturers.

Gates And Inverters - Multi-Function, Configurable FAQ

What is the default state of the outputs if the inputs are left open?

The device incorporates internal input pulldown resistors that pull the inputs to a defined logic level, preventing undefined states when inputs are floating.

Does the MC10EL12 support both single-ended and differential signaling?

The MC10EL12 is a differential driver with dual differential outputs (Qa/Qa and Qb/Qb), designed primarily for differential ECL signaling applications.
