SN74159N

The SN74159N is a 4-to-16 Decoder utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen mutually exclusive open-collector outputs when both the strobe inputs, G1\ and G2\ are low. The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input low. When either strobe input is high, all outputs are high. These demultiplexers are ideally suited for implementing MOS memory decoding or for interfacing with discrete memory address drivers. It is fully compatible for use with the most other TTL circuits. Input clamping diodes are provided to minimize transmission line effects and thereby simplify system design. Input buffers are used to lower the fan-in requirement to only one normalized series 74 load in low level state is available from each of the sixteen outputs.
