Hot-selling and scarce MC10125FNR2 Quad MECL to TTL Translator PLCC20 spot stock

Product Descriptions

The MC10125 is a quad translator for interfacing data and control signals between the MECL section and saturated logic sections of digital systems. The MC10125 incorporates differential inputs and Schottky TTL “totem pole” outputs. Differential inputs allow for use as an inverting/ non–inverting translator or as a differential line receiver. The VBB reference voltage is available on pin 1 for use in single–ended input biasing. The outputs of the MC10125 go to a low logic level whenever the inputs are left floating.

Power supply requirements are ground, +5.0 Volts and –5.2 Volts. Propagation delay of the MC10125 is typically 4.5 ns. The MC10125 has fanout of 10 TTL loads. The dc levels are MECL 10,000 in and Schottky TTL, or TTL out. This device has an input common mode noise rejection of ± 1.0 Volt.

An advantage of this device is that MECL level information can be received, via balanced twisted pair lines, in the TTL equipment. This isolates the MECL logic from the noisy TTL environment. This device is useful in computers, instrumentation, peripheral controllers, test equipment and digital communications systems.

• PD = 380 mW typ/pkg (No Load) 

• tpd = 4.5 ns typ (50% to + 1.5 Vdc out) 

• tr, tf = 2.5 ns typ (1.0 V to 2.0 V)
