MC100EP11DTG

Clock Buffers, Drivers Overview

The MC100EP11DTG is a differential 1:2 fanout buffer from the onsemi MC100 Series, housed in an 8-lead TSSOP package. It supports PECL mode with VCC ranging from 3.0 V to 5.5 V (VEE = 0 V) and NECL mode with VEE from −3.0 V to −5.5 V (VCC = 0 V). The device features a typical propagation delay of 220 ps and a maximum clock frequency exceeding 3 GHz. DC characteristics at VCC = 3.3 V include a negative power supply current of 26 mA to 46 mA across the operating temperature range of −40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Test and measurement instrumentation requiring low jitter

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'DTG' corresponds to the TSSOP-8 package configuration as listed in the manufacturer's ordering information table. Confirm RoHS compliance status and check for any discontinuation notices or recommended new design restrictions associated with this specific part number variant before finalizing procurement plans.

Clock Buffers, Drivers Selection Notes

Select the MC100EP11DTG when a differential 1:2 fanout buffer with high-speed AC performance is required. Ensure the system power supply aligns with either the PECL range (3.0 V–5.5 V) or NECL range (−3.0 V to −5.5 V). Consider the thermal resistance values provided for the TSSOP-8 package if operating near the upper temperature limits.

Clock Buffers, Drivers Part Context

This component belongs to the MC10/100EP11 family, which includes pin-compatible variants such as MC10EP11DG and MC100EP11DR2G. The MC100 Series specifically incorporates temperature compensation compared to the standard MC10 series. The DTG suffix denotes the TSSOP-8 surface-mount package type.

Clock Buffers, Drivers FAQ

What is the internal resistor configuration for the inputs?

The device contains an internal input pulldown resistor of 75 kΩ and an internal input pullup resistor of 37.5 kΩ.

How do the outputs behave when the inputs are left open?

When inputs are open or at VEE, the Q outputs will default LOW due to the open input default state feature.

What is the maximum continuous output current rating?

The maximum continuous output current is rated at 50 mA, with a surge current capability of 100 mA.
