MM54HCT155

The MM54HCT155 is a high speed silicon gate CMOS decoder/demultiplexer. It features dual t-to-4 line demultiplexers with independent strobes and common binary address inputs. When both sections are enabled by the strobes, the common address inputs select and route associated input data to the appropriate output of each section. The individual strobes of MM54HCT155 permit activating or inhibiting each of the 4-bit sections as desired. Data applied to input C1 of MM54HCT155 is inverted at its outputs and data applied to C2 is "non-inverted" at its outputs. If the strobes (G1 and G2) are connected together and the Data Inputs are connected together, the device can be used as a 3-to-8 line decoder or a 1-to-8 line demultiplexer.

Features of the MM54HCT155 are:(1)applications:dual 2-to-4 line decoder,dual 1-to-4 line demultiplexer,3-to-8 line decoder,1-to-8 line demultiplexer; (2)typical propagation delay: 22 ns; (3)low quiescent current: 80 pA maximum (74HCT Series).All inputs to the decoder are protected from damage due to electrostatic discharge by diodes to V}} and ground. The device is capable of driving 10 low power Schottky TTL equivalent loads.

The absolute maximum ratings of the MM54HCT155 can be summarized as:(1)supply voltage:-0.5 to 7.0V;(2)storage temperature range:-65 to +150;(3)DC input voltage:-1.5 to Vcc+1.5V;(4)DC output voltage:-0.5 to Vcc+0.5V;(5)power dissipation:600mW.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
