About this product
The 7438 is a TTL quad 2-input NAND buffer with open-collector outputs in a 14-pin DIP package. Open-collector outputs let several outputs share one line (wired-AND) and drive higher loads on a bus, which makes it useful for classic digital logic projects and lab work.

Frequently asked questions
What is the price of 7438 Quad 2-Input NAND Buffer with Open-Collector Outputs DIP-14 in Egypt?
7438 Quad 2-Input NAND Buffer with Open-Collector Outputs DIP-14 currently costs 18 EGP in Egypt.
Where can I buy 7438 Quad 2-Input NAND Buffer with Open-Collector Outputs DIP-14 in Egypt?
7438 Quad 2-Input NAND Buffer with Open-Collector Outputs DIP-14 is available from Makers Electronics. Compare the offers above to find the best price.
Why do the outputs need a pull-up resistor?
Open-collector outputs can only pull the line low. Connect a pull-up resistor from each output to the logic supply (typically 5 V for TTL) so the line goes high when no gate pulls it low.
Can I use it with a 3.3 V microcontroller?
The 7438 is designed for 5 V TTL logic. To interface it with 3.3 V boards, check input thresholds and the pull-up voltage on the datasheet, and use level shifting where needed.
