MC14504BFELG

Translators, Level Shifters Overview

The MC14504BFELG is a hex non-inverting level shifter utilizing CMOS technology, housed in a 16-lead SOEIAJ surface-mount package. It operates with dual power supplies (VCC and VDD) ranging from 3 to 18 Vdc. The device translates TTL signals to CMOS logic levels or shifts between different CMOS voltage levels. Key electrical parameters include a maximum propagation delay of 340 ns at 5 V supply, input current of ±0.1 µA, and output drive capabilities supporting low-power TTL loads.

Translators, Level Shifters FAQ

How does the MODE pin determine the translation type?

Connecting the MODE pin to VCC configures the device for TTL-to-CMOS translation, while connecting it to VSS enables CMOS-to-CMOS translation.

What is the function of the VCC and VDD pins?

VCC sets the input signal logic levels, whereas VDD selects the output voltage levels, allowing independent control over input and output thresholds.
