General Description

These BCD-to-decimal decoders consist of eight inverters and ten, four-input NAND gates. The inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of input logic ensures that all outputs remain off for all invalid (10–15) input conditions.

Features
■ Diode clamped inputs
■ Also for application as 4-line-to-16-line decoders;
   3-line-to-8-line decoders
■ All outputs are high for invalid input conditions
■ Typical power dissipation 140 mW
■ Typical propagation delay 17 ns

These genuine and original National parts are now obsolete.

PLEASE NOTE!

These parts came to us as part of a lot of surplus stock from a large ‘Mispec’ type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’, they are however pristine, stored with us sealed in original packaging, the photographs are representative of their general condition, being of some of our actual stock, and, as with all our products they come with a full guarantee.
