SN54LVC138AD

The SN54LVC138AD is designed as a 3-line to 8-line decoder/demultiplexer for 2.7V to 3.6V Vcc operation. SN54LVC138AD is for high performance memory decoding or data-routing applications requiring very short propagation delay times. In high performance memory systems, these decoders minimize the effects of system decoding.

SN54LVC138AD has seven features. (1)EPIC (enhanced performance implanted CMOS) submicron process. (2)ESD protection exceeds 2000V per MIL-STD-883 method 3015; exceeds 200V using machine model. (3)Latch-up performance exceeds 250mA per JESD 17. (4)Typical Volp (output ground bounce)<0.8V at Vcc=3.3V. (5)Typical Vohv (output Voh undershoot)>2V at Vcc=3.3V. (6)Its inputs accept voltages to 5.5V. (7)Package small outline. Those are all the main features.

Some absolute maximum ratings of SN54LVC138AD have been concluded into several points as follow. (1)Its supply voltage range would be from -0.5V to 6.5V. (2)Its input voltage range would be from -0.5V to 6.5V. (3)Its output voltage range would be from -0.5V to Vcc+0.5V. (4)Its input clamp current would be -50mA. (5)Its output clamp current would be -50mA. (6)Its continuous output current would be +/-50mA. (7)Its continuous current through Vcc or GND would be +/-100mA. (8)Its packae thermal impedance would be 113°C/W. (9)Its storage temperature range would be from -65°C to 150°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of SN54LVC138AD are concluded as follow. (1)Its output high voltage would be min Vcc-0.2V at Vcc=2.7V to 3.6V at Ioh=-100uA and it would be min 2.2V at Vcc=2.7V and Ioh=-12mA. (2)Its output voltage low would be max 0.2V at Vcc=2.7V to 3.6V, Iol=100uA and would be max 0.4V at Vcc=2.7V, Iol=12mA. (3)Its input leakage current would be max +/-5uA. (4)Its input capacitance would be typ 5pF. And so on. If you have any question or suggestion or want to know more information about SN54LVC138AD please contact us for details. Thank you!
