Frequently Asked Questions
What is the SN74HC253N and what does it do?
The SN74HC253N is a dual 4-line to 1-line data selector/multiplexer with 3-state outputs from Texas Instruments. It contains two independent 4-to-1 multiplexers in a single 16-pin DIP package, allowing selection of one of four data inputs per channel based on two shared select lines. It operates from 2V to 6V supply voltage.
What are the key electrical specifications of the SN74HC253N?
The SN74HC253N supports a load capacitance (CL) of up to 150pF and provides a maximum low-level output current (I(ol)) of 7.8mA. It belongs to the HC/UH CMOS logic family, operates across a 2V to 6V supply range, and is housed in a 16-pin R-PDIP-T16 package. The device meets JESD-609 Code e4 for RoHS compliance.
What are typical applications for the SN74HC253N?
The SN74HC253N is commonly used in data bus multiplexing, memory address selection, signal routing in embedded systems, and FPGA prototyping. Its 3-state output capability makes it ideal for shared-bus architectures in microcontroller and DSP systems, as well as test equipment and communication interface designs.
Can multiple SN74HC253N devices share a common data bus?
Yes. The 3-state outputs of the SN74HC253N allow its outputs to be disabled (high-impedance state), enabling multiple devices to be connected to a common data bus without signal contention. This is controlled via the output-enable pins, making it straightforward to implement bus arbitration in digital systems.
What package does the SN74HC253N come in and what are alternatives?
The SN74HC253N comes in a 16-pin dual-in-line (DIP) package (JESD-30 Code R-PDIP-T16), suitable for through-hole PCB assembly. For surface-mount designs, Texas Instruments offers the SN74HC253D (SOIC-16) and SN74HC253PW (TSSOP-16) as direct functional equivalents with the same logic operation.
