INTEGRATED CIRCUITS 74LV154 4-to-16 line decoder/demultiplexer Product specification Supersedes data of 1997 Mar 07 IC24 Data Handbook 1998 Apr 28 Philips Semiconductors Product specification 4-to-16 line decoder/demultiplexer 74LV154 FEATURES DESCRIPTION • Optimized for low voltage applications: 1.0 to 3.6 V • Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V • Typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, The 74LV154 is a low-voltage CMOS device and is pin and function compatible with 74HC/HCT154. The 74LV154 decoders accept four active HIGH binary address inputs (A0 to A3) and provide 16 mutually exclusive active LOW outputs(Y0 to Y15). Tamb = 25°C • Typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, The 2-input enable inputs (E0, E1) 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. Tamb = 25°C • 16-line demultiplexing capability • Decodes 4 binary-coded inputs into one of 16 mutually The enable input has two AND’ed inputs which must be LOW to enable the outputs. exclusive outputs • 2-input enable gate for strobing or expansion • Output capability: standard • ICC category: MSI The 74LV154 can be used as a 1-to-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.
