Product Details
description
These data selectors/multiplexers contain inverters and drivers to
supply full data selection to the four output gates. A separate
strobe (G) input is provided. A 4-bit word is selected from one of
two sources and is routed to the four outputs. The ′ALS157A and
SN74AS157 present true data. The ′ALS158 and SN74AS158 present
inverted data to minimize propagation delay time.
• Buffered Inputs and Outputs
• Package Options Include Plastic Small-Outline (D) Packages,
Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic
(J) 300-mil DIPs
