21990 Jan 08 8531155 98493

FEATURES

16-line demultiplexing capability

Mutually exclusive outputs

2-input enable gate for strobing or expansion

DESCRIPTIONThe 74F154 decoder accepts four active High binary address inputs

and provides 16 mutually exclusive active Low outputs. The 2-input

Enable (E0, E1) gate can be used to strobe the decoder to eliminate

the normal decoding glitches on the outputs, or it can be used for

expansion of the decoder. The enable gate has two ANDed inputs

which must be Low to enable the outputs.

The 74F154 can be used as 1-of-16 demultiplexer by using one of

the Enable inputs as the multiplexed data input. When the other

Enable is Low, the addressed output will follow the state of the

applied data.

NOTES:1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.2. All typical values are at VCC = 5V, Tamb = 25C.3. Not more than one output should be shorted at a time. For testing IOS, the use of high-speed test apparatus and/or sample-and-hold

techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shortingof a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In anysequence of parameter tests, IOS tests should be performed last.
