Description

The 74LV153N belongs to 74LV153 fammily which is a low-voltage CMOS device that is pin and function compatible with 74HC/HCT153. The 74LV153 is a dual 4-input multiplexer which selects 2 bits of data from up to four sources selected by common data select inputs (S0, S1). The 74LV153 is the logic implementation of a 2-pole, 4-position switch, where the position of the switch, is determined by the logic levels applied to S0 and S1. The logic equations for the outputs are: 1Y=1E.(1I0.S1.S0+1I1.S1.S0+1I2.S1.S0+1l3.S1.S0) 2Y=2E.(2I0.S1.S0+2I1.S1.S0+2I2.S1.S0+2I3.S1.S0). The outputs (1Y, 2Y) are forced LOW when the corresponding output enable inputs are HIGH. The state of the select inputs would determine the particular register from which the data came. An alternative application is a function generator. The device can generate two functions or three variables. This is useful for implementing highly irregular random logic. The 74LV153 can be used to move data to a common output bus from a group of registers. The two 4-input multiplexer circuits of the 74LV153N have individual active LOW output enable inputs (1E, 2E) which can be used to strobe the outputs independently.

The features of 74LV153N 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)non-inverting outputs; (6)separate enable for each output; (7)common select inputs; (8)permits multiplexing from n lines to 1 line; (9)enable line provided for cascading (n lines to 1 line); (10)output capability: standard; (11)ICC category: MSI.

The absolute maximum ratings of 74LV153N are (1)VCC DC supply voltage: -0.5 to +4.6 V; (2)±IIK DC input diode current(VI < -0.5 or VI > VCC + 0.5V): 20mA; (3)±IOK DC output diode current(VO < -0.5 or VO > VCC + 0.5V): 50mA; (4)±IO DC output source or sink current -bus driver outputs(-0.5V < VO < VCC + 0.5V): 25mA; (5)±IGND, ±ICC DC VCC or GND current for types with bus driver outputs: 50mA; (6)Tstg storage temperature range of the 74LV153N: -65 to +150 °C; (7)power dissipation per package for temperature range: -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 74LV153N at these or any other conditions beyond those indicated under arecommended 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 may be exceeded if the input and output current ratings are observed.)
