www.DataSheet4U.com RD74LVC138B 3-to-8-line Decoder / Demultiplexer REJ03D0502–0200 Rev.2.00 Jan. 14, 2005 Description The RD74LVC138B has three binary select inputs in a 16 pin package. If the device is enabled these inputs determine which one of the eight normally high outputs will go low. Two active low and one active high enables are provided to ease the cascading of decoders. Low voltage and high-speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation. Features VCC = 1.65 V to 5.5 V All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±4 mA (@VCC = 1.65 V) ±8 mA (@VCC = 2.3 V) ±12 mA (@VCC = 2.7 V) ±24 mA (@VCC = 3.0 V to 5.5 V) Ordering Information Part Name RD74LVC138BFPEL RD74LVC138BTELL Package Type SOP–16 pin (JEITA) TSSOP–16 pin Package Code FP–16DAV TTP–16DAV FP T Package Abbreviation Taping Abbreviation (Quantity) EL (2,000 pcs/reel) ELL (2,000 pcs/reel) Function Table Inputs Enable G1 X X L H H H H H H H H H: L: X: G2A X H X L L L L L L L L Low level Immaterial G2B H X X L L L L L L L L C X X X L L L L H H H H Select B X X X L L H H L L H H A X X X L H L H L H L H Y0 H H H L H H H H H H H Y1 H H H H L H H H H H H Y2 H H H H H L H H H H H Y3 H H H H H H L H H H H Outputs Y4 H H H H H H H L H H H Y5 H H H...
