MC14504BDTR2G

Translators, Level Shifters Overview

The MC14504BDTR2G is a hex non-inverting level shifter utilizing CMOS technology, housed in a 16-pin TSSOP package. It translates TTL signals to CMOS logic levels or shifts between different CMOS voltage domains. The device operates with VDD and VCC supply voltages ranging from 3V to 18V. Input thresholds are configurable for TTL compatibility via the MODE pin. Propagation delays vary by shifting mode; typical values include 140ns for TTL-to-CMOS high-to-low transitions at 10V/15V supplies.

Translators, Level Shifters Feature Summary

• Translates signal levels up from low voltage or down from high voltage domains
• Configurable input threshold allows direct interface with TTL logic standards
• Diode-protected inputs prevent damage during power-up or power-down sequencing
• Capable of driving standard low-power TTL loads without external components

Translators, Level Shifters Applications

• Interface circuits connecting TTL microcontrollers to higher voltage CMOS peripherals
• Level translation between distinct CMOS logic families operating at different supply rails
• Signal buffering in mixed-voltage digital systems requiring unidirectional data transfer

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'DT' confirms the TSSOP-16 package configuration. Confirm RoHS compliance status as indicated by the 'G' marking. Ensure the ordering code matches the required tape and reel quantity specifications for automated assembly processes.

Translators, Level Shifters Selection Notes

Select this component when unidirectional level shifting between TTL and CMOS or varying CMOS voltages is required. The dual-supply architecture allows independent setting of input and output logic thresholds. Verify that the maximum supply voltage limits accommodate the system's highest operating rail.

Translators, Level Shifters FAQ

How does the MODE pin affect operation?

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

Is power sequencing required?

No sequencing is required on the power supplies or inputs for power-up or power-down operations due to the diode-protected input structure.
