DILC-24 FPC-24 ORDER CODES PACKAGE FM EM DILC FPC M54HC154D M54HC154K M54HC154D1 M54HC154K1 A binary code applied to the four inputs (A to D) provides a low level at the selected one of sixteen outputs excluding the other fifteen outputs, when both the strobe inputs, G1 and G2, are held low. When either strobe input is held high, the decoding function is inhibited to keep all outputs high. The strobe function makes it easy to expand the decoding lines through cascading, and simplifies the design of address decoding circuits in memory control systems. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
