产品概述
The SN74AS298A is a quadruple 2-input multiplexer with storage
that provides essentially the equivalent functional capabilities of
two separate MSI functions (SN74AS157 and ´AS175A) in a 16-pin
package.When the word-select (WS) input is low, word 1 (A1, B1, C1, D1) is
applied to the flip-flops. A high input to WS causes the selection of
word 2 (A2, B2, C2, D2). The selected word is clocked to the output
terminals on the negative-going edge of the clock pulse.The SN74AS298A is characterized for operation from 0°C to
70°C. a1, a2, etc. = the level of steady-state input at A1, A2,
etc.
QA0, QB0, etc. = the level of QA,
QB, etc. entered on the most recent transition of
CLK
