Dual 4:1 multiplexer in a through-hole DIP
The CD74ACT253E is a dual 4:1 multiplexer from the 74ACT family, selecting one of four data inputs per section under common address control.
Package and board integration
Housed in a 16-pin DIP with 0.300-inch (7.62mm) body width, the CD74ACT253E is a through-hole part that suits prototyping boards, socketed designs, or legacy PCB layouts where a surface-mount multiplexer would require a board respin. The 16-PDIP supplier package code matches the standard DIP-16 footprint.
Lifecycle and compliance status
Texas Instruments lists the CD74ACT253E as an active product with no end-of-life notice. It is ROHS3 compliant, meaning no restricted substances above the exemption thresholds — suitable for new designs requiring RoHS conformance.
