description

These monolithic quadruple two-input multiplexers with storage provideessentially the equivalent functional capabilities of two separate MSI functions(SN54157/SN74157 or SN54LS157/SN74LS157 and SN54175/SN74175 or SN54LS175/SN74LS175)in a single 16-pin package.

When the word-select input is low, word 1 (A1, B1, C1, D1) is applies tothe flip-flops. A high input to word select will cause the selection of word2 (A2, B2, C2, D2). The selected word is clocked to the output terminals onthe negative-going edge of the clock pulse.

Typical power dissipation is 195 milliwatts for the '298 and 65 milliwattsfor the 'LS298. SN54298 and SN54LS298 are characterized for operation overthe full military temperature range of -55°C to 125°C; SN74298 andSN74LS298 are characterized for operation from 0°C to 70°C.
