Alternate Parts for SN74LS273DW
This table gives cross-reference parts and alternative options found for SN74LS273DW. The Form Fit Function (FFF) tab will give you the options that are more likely to serve as direct pin-to-pin alternates or drop-in parts. The Functional Equivalents tab will give you options that are likely to match the same function of SN74LS273DW, but it may not fit your design. Always verify details of parts you are evaluating, as these parts are offered as suggestions for what you are looking for and are not guaranteed.
SN74LS273DW Frequently Asked Questions (FAQ)
-
The SN74LS273DW can handle clock frequencies up to 35 MHz.
-
To ensure proper initialization, connect the CLR (clear) input to a power-on reset circuit or a manual reset switch. This ensures that the flip-flops are reset to a known state during power-up.
-
The recommended operating voltage range for the SN74LS273DW is 4.75V to 5.25V.
-
No, the SN74LS273DW is not designed to operate at 3.3V. It is a 5V device and should only be used in systems with a 5V power supply.
-
The SN74LS273DW has TTL-compatible inputs and outputs, so it can be directly interfaced with most microcontrollers and logic devices. Ensure that the voltage levels and logic levels are compatible.
