ITEM SPECIFICS
Brand: Fairchild Semiconductor
Model: 9N23/7423
MPN: 9N23/7423
Type: Dual 4-Input Positive-NOR Gate with Strobe
Logic Family: Standard TTL (7400 series)
Number of Gates: 2
Inputs per Gate: 4
Package: 16-Pin Plastic DIP
Mounting: Through-Hole
Supply Voltage: 5V nominal
Operating Temperature: 0°C to 70°C
Condition: New
Quantity: 10
DESCRIPTION
Lot of 10 new old stock Fairchild Semiconductor 9N23/7423 dual 4-input positive-NOR gates with strobe in 16-pin plastic DIP. Each is marked "9N23/7423" with Fairchild's "PC F" marking. Photos show a representative unit with date code 7304, which places manufacture in 1973; date codes may vary within the lot. Never installed. Leads show light storage discoloration, as pictured.
Fairchild sold its 7400-series equivalents under its own 9N numbering, so these parts carry both the Fairchild 9N23 number and the industry-standard 7423 number.
Features:
Two 4-input NOR gates, each with a strobe input
Standard 7400-series TTL, 5V logic
16-pin plastic DIP, through-hole
Original Fairchild manufacture, 1970s vintage
Commercial temperature range, 0°C to 70°C
10 pieces
Compatibility:
Direct replacement for 7423, SN7423, and Fairchild 9N23 in 16-pin DIP sockets. The 7425 performs the same dual 4-input NOR-with-strobe function but is a 14-pin part, so it is not a drop-in substitute.
Q&A
Q: What is the 9N23/7423?
A: A Fairchild dual 4-input NOR gate with strobe, in standard TTL, packaged in a 16-pin plastic DIP.
Q: What replaces a 7423?
A: These parts are a direct replacement for 7423, SN7423, and Fairchild 9N23.
Q: Is the 7423 the same as the 7425?
A: Same logic function, different package. The 7423 is 16-pin; the 7425 is 14-pin. They are not pin-compatible.
Q: How old are these parts?
A: The pictured unit is date coded 7304, which places manufacture in 1973. Date codes may vary within the lot.
