This table gives cross-reference parts and alternative options found for SN74LS193D. 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 SN74LS193D, 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.
SN74LS193D Frequently Asked Questions (FAQ)
-
The maximum clock frequency of the SN74LS193D is 5 MHz, but it can be operated at higher frequencies with proper signal integrity and layout considerations.
-
To ensure proper reset, the reset input (R) should be pulled low for at least 10 ns, and then released. The counter will reset to zero when the reset input is low.
-
The SN74LS193D is a 4-bit binary counter, which means it can count up to 15 (1111 in binary).
-
Yes, the SN74LS193D can be used as a divider by connecting the clock input to the output of a previous stage. However, the divide ratio will be limited to powers of 2 (2, 4, 8, etc.).
-
To cascade multiple counters, connect the carry-out (CO) of one counter to the clock input of the next counter. Ensure that the counters are properly synchronized and that the clock signal is properly distributed.
