ITEM SPECIFICS
Brand: National Semiconductor
MPN: DM74LS157N
Type: Quad 2-Line to 1-Line Data Selector/Multiplexer
Logic Family: 74LS
Package: PDIP-16 / DIP-16
Number of Pins: 16
Mounting Style: Through-Hole
Output Type: Non-Inverting
Condition: New Open Box
Additional Marking: 939
Quantity: 10
DESCRIPTION
Lot of 10 National Semiconductor DM74LS157N integrated circuits in new open-box condition.
The DM74LS157N is a quad 2-line-to-1-line data selector/multiplexer with four 2:1 channels and non-inverting outputs. Each device uses a 16-pin through-hole DIP package.
The devices are marked DM74LS157N with the National Semiconductor logo. Leads and bodies may show light cosmetic signs of storage or handling. No electrical testing is represented in this listing.
DISCLAIMER
New open box. Review all photos for exact condition and markings. Ships fast with tracking. 30-day returns accepted; buyer pays return shipping.

COMPATIBILITY & CROSS-REFERENCE
The National Semiconductor DM74LS157N is a 74LS157-family quad 2-line-to-1-line data selector/multiplexer with true (non-inverting) outputs and a separate strobe input, in a 16-pin DIP for 5V TTL logic. Texas Instruments SN74LS157N is the same function and package, so it can serve as a cross-reference in 74LS157 sockets. It is not interchangeable with the 74LS158, which presents inverted data, and it is not a drop-in for 74HC157 or 74S157 devices, which have different electrical characteristics. This lot suits repair shops and restorers who need several 74LS157 devices for vintage computers, arcade boards, and TTL logic repair. Confirm the pinout against your board before installing.
Q: What does the DM74LS157N replace?
A: Other 74LS157 quad 2:1 data selector/multiplexers in 16-pin DIP sockets, including SN74LS157N.
Q: What is the difference between the 74LS157 and the 74LS158?
A: The 74LS157 presents true data at its outputs, while the 74LS158 presents inverted data.
Q: How many are included?
A: This listing is a lot of 10 DM74LS157N devices, new open box and sold as shown.
