U74HC138

UNISONIC TECHNOLOGIES CO., LTD U74HC138 3-TO-8 LINE DECODERS / DEMULTIPLEXERS  DESCRIPTION The U74HC138 decodes a three-bit Address to 1-of-8 active-low outputs. This device features three Chip Select inputs, two active-low and one active-high, to facilitate the demultiplexing, cascading, and chip-selecting functions. The demultiplexing function is accomplished by using the address inputs to select the desired device output. One of the Chip Selects is used as a data input while the other Chip Selects are held in their active states.  FEATURES * Operate from 2.0V ~ 6.0V * Low Input Current: 100nA Max * Low Quiescent Current: 8μA Max * Typ tPD=15ns * Output Drive:4mA @ 5V  ORDERING INFORMATION Ordering Number Lead Free Halogen Free U74HC138L-D16-T U74HC138G-D16-T U74HC138L-S16-R U74HC138G-S16-R U74HC138L-R16-R U74HC138G-R16-R U74HC138L-P16-R U74HC138G-P16-R Package DIP-16 SOP-16 SSOP-16 TSSOP-16 CMOS IC DIP-16 SOP-16 SSOP-16 TSSOP-16 Packing Tube Tape Reel Tape Reel Tape Reel www.unisonic.com.tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-614.F U74HC138  MARKING Package DIP-16 SOP-16 TSSOP-16 CMOS IC Marking 16 15 14 13 12 11 10 UTC U74HC138 9 1 2345 6 7 8 Date Code L: Lead Free G: Halogen Free Lot Code SSOP-16  PIN CONFIGURATION A0 1 A1 2 A2 3 E1 4 E2 5 E3 6 Y7 GND 7 8 16 VCC 15 Y0 14 Y1 13 Y2 12 Y3 11 Y4 10 Y5 9 Y6  FUNCTION TABLE INPUTS OUTPUTS E1 E2 E3 A0 A1 A2 Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 HXXXXXHHHHHHHH XHXXXXHHHHHHH...
