This device is a 3 to 8 line decoder with latches on the three address inputs. When GL goes from low DILC-16 FPC-16 ORDER CODES PACKAGE FM EM DILC FPC M54HC137D M54HC137K M54HC137D1 M54HC137K1 to high, the addresses present at the select inputs (A, B, and C) is stored in the latches. As long as GL remains high no address changes will be recognized. Output enable pins G1 and G2, control the state of the outputs independently of the select or latch-enable inputs. All the outputs are high unless G1 is high and G2 is low. The 54HC137 is ideally suited for the implementation of glitch-free decoders in stored-address application in bus oriented systems. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
