74LV154N

The 74LV154N belongs to 74LV154 family which is a low-voltage CMOS device and is pin and function compatible with 74HC/HCT154 and the 74LV154 decoders accept four active HIGH binary address inputs (A0 to A3) and provide 16 mutually exclusive active LOW outputs(Y0 to Y15). 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. The enable input has two AND'ed inputs which must be LOW to enable the outputs. 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.

The features of 74LV154N can be summarized as (1)optimized for low voltage applications: 1.0 to 3.6 V; (2)accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V; (3)typical VOLP (output ground bounce) < 0.8 V at VCC = 3.3 V, Tamb = 25°C; (4)typical VOHV (output VOH undershoot) > 2 V at VCC = 3.3 V, Tamb = 25°C; (5)16-line demultiplexing capability; (6)decodes 4 binary-coded inputs into one of 16 mutually exclusive outputs; (7)2-input enable gate for strobing or expansion; (8)output capability: standard; (9)ICC category: MSI.

The absolute maximum ratings of 74LV154N are (1)VCC DC supply voltage: -0.5 to +4.6V; (2)±IIK DC input diode current(VI < -0.5 or VI > VCC + 0.5V): 20 mA; (3)±IOK DC output diode current(VO < -0.5 or VO > VCC + 0.5V): 50 mA; (4)±IO DC output source or sink current- standard outputs(-0.5V < VO < VCC + 0.5V): 25 mA; (5)±IGND, ±ICC DC VCC or GND current for types with-standard outputs: 50 mA; (6)Tstg storage temperature range: -65 to +150 °C; (7)Ptot power dissipation per package for temperature range of the 74LV154N: -40 to +125°C,plastic DIL above +70°C derate linearly with 12mW/K/plastic mini-pack (SO) above +70°C derate linearly with 8 mW/K/plastic shrink mini-pack (SSOP and TSSOP)above +60°C derate linearly with 5.5 mW/K: 750/500/400mW.(1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability. 2. The input and output voltage ratings of the 74LV154N may be exceeded if the input and output current ratings are observed.).
