Texas Instruments 74HCT158
The ’HC157, ’HCT157, ’HC158, and ’HCT158 are quad 2input multiplexers which select four bits of data from two sources under the control of a common Select input (S). The Enable input (E) is active Low.| Part No. | 74HCT158 |

DESCRIPTION
● Common Select Inputs● Separate Enable Inputs
● Buffered inputs and Outputs
● Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LSTTL Loads - Bus Driver Outputs . . . . . . . . . . . . . 15 LSTTL Loads
● Wide Operating Temperature Range . . . -55oC to 125oC
● Balanced Propagation Delay and Transition Times
● Significant Power Reduction Compared to LSTTL Logic ICs The Enable input (E) is active Low. When (E) is High, all of the outputs in the 158, the inverting type, (1Y-4Y) are forced High and in the 157, the non-inverting type, all of the outputs (1Y-4Y) are forced Low, regardless of all other input conditions. Moving data from two groups of registers to four common output buses is a common use of these devices. The state of the Select input determines the particular register from which the data comes. They can also be used as function generators.
● HC Types - 2V to 6V Operation - High Noise Immunity: NIL = 30%, NIH = 30%of VCC a...
