Additional Infomation About Product

MC74AC138, MC74ACT138 1-of-8 Decoder/Demultiplexer The MC74AC138/74ACT138 is a highspeed 1of8 decoder/demultiplexer. This device is ideally suited for highspeed bipolar memory chip select address decoding. www.onsemi.com The multiple input enables allow parallel expansion to a 1of24 decoder using just three MC74AC138/74ACT138 devices or a MARKING 1of32 decoder using four MC74AC138/74ACT138 devices and one DIAGRAMS inverter. 16 Demultiplexing Capability SOIC16 xxx138G D SUFFIX Multiple Input Enable for Easy Expansion 16 AWLYWW CASE 751B Active LOW Mutually Exclusive Outputs 1 1 Outputs Source/Sink 24 mA 16 ACT138 Has TTL Compatible Inputs xxx These are PbFree Devices TSSOP16 138 16 DT SUFFIX ALYW CASE 948F 1 V O O O O O O O CC 0 1 2 3 4 5 6 1 16 15 14 13 12 11 10 9 xxx = AC or ACT A = Assembly Location WL or L = Wafer Lot Y = Year WW or W = Work Week G or = PbFree Package (Note: Microdot may be in either location) 1 2 3 4 567 8 A A A E E E O GND 0 1 2 1 2 3 7 Figure 1.
