MC14504BDT

Translators, Level Shifters Overview

The MC14504BDT is a hex non-inverting level shifter utilizing CMOS technology, housed in a 16-pin TSSOP package. It facilitates signal translation between TTL and CMOS logic levels or between different CMOS voltage domains. The device operates with dual supply voltages (VCC and VDD) ranging from 3 to 18 Vdc. Key electrical parameters include a maximum propagation delay of 340 ns at 25°C with a 50 pF load, input current of ±0.1 µA, and output drive capabilities sufficient for low-power TTL loads.

Translators, Level Shifters Feature Summary

• Performs unidirectional level shifting from lower to higher voltage domains or vice versa
• Configurable input threshold allows compatibility with standard TTL logic signals
• Eliminates the need for power supply sequencing during power-up or power-down cycles
• Features diode-protected inputs connected to the VSS rail

Translators, Level Shifters Applications

• Translating TTL signals to CMOS logic levels
• Interfacing CMOS circuits operating at one voltage level to another
• Driving low-power Schottky TTL loads

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DT' corresponds to the TSSOP-16 package configuration required for your PCB layout. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure that the ordering documentation matches the exact part number to avoid discrepancies in package type or lead finish specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing mixed-voltage logic families requiring unidirectional translation. The dual-supply architecture allows independent setting of input and output voltage thresholds. Verify that the application does not require bidirectional data flow, as this device supports only single-direction signal transfer.

Translators, Level Shifters Part Context

This device belongs to the MC14504B series of hex level shifters manufactured by onsemi. It is designed to bridge communication gaps between different logic standards, specifically enabling TTL outputs to drive CMOS inputs or allowing CMOS-to-CMOS translation across varying supply rails without external components.

Translators, Level Shifters FAQ

How is the direction of level translation determined?

Translation direction is determined by the relative values of the VCC and VDD supply pins. Setting VDD higher than VCC performs up-conversion, while setting VCC higher than VDD performs down-conversion.

What is the function of the MODE pin?

The MODE pin selects the input logic threshold characteristics. Connecting it to VCC configures the device for TTL-compatible input levels, while connecting it to VSS configures it for standard CMOS input levels.
