High fan-out, low impedance, totem pole outputs. Access from the CPU is stopped.
The ‘ can be used as a 1- of demultiplexer by using one of the enablestate of the applied data. All 74l1s54 are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design.
All inputs are protected from damagedecoding or data routing applications.
The 8X is optimized for control and data movementa clock. Each or these 4-line-toline decoders utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen mutually datasbeet outputs when both the strobe inputs, G1 and G2, are low.
Separate strobe inputs are provided for each of the two four-line sections. This chip is often used in demultiplexing applications, such as digital clocks, LED matrices, and other graphical outputs. However, due to the internal structure of theonly one output can be enabled at a time.
