Description

The DM74LS154WM  is one of the DM74LS154 series.Each of these 4-line-to-16-line decoders utilizes TTL cir-cuitry to decode four binary-coded inputs into one of six-teen mutually exclusive 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 out-put 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 high-performance memory decod-ers. All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design.

Features of the DM74LS154WM are:(1)Decodes 4 binary-coded inputs into one of 16 mutually exclusive outputs; (2)Performs the demultiplexing function by distributing data from one input line to any one of 16 outputs; (3)Input clamping diodes simplify system design; (4)High fan-out, low-impedance, totem-pole outputs; (5)Typical propagation delay:3 levels of logic 23 ns;Strobe 19 ns; (6)Typical power dissipation 45 mW.

The absolute maximum ratings of the DM74LS154WM can be summarized as:(1)Supply Voltage: 7V; (2)Input Voltage :7V; (3)Operating Free Air Temperature Range :0°C to +70°C; (4)Storage Temperature Range: -65°C to +150°C..If you want to know more information about DM74LS154WM, please download the datasheet in www.seekic.com or www.chinaicmart.com.
