It is a 3-to-8 line decoder that decodes one of the 8 output lines according to the requirements of 3 select and 3 enables.
Features
High-speed operation: tpd=16ns (standard) (VCC=5V)
Low Current Consumption: ICC = 4μA (Max) (Ta = 25℃)
High noise allowance: VNIH = VNIL=28% VCC (min)
High fanout: Can drive 10 LSTTL directly
Symmetric output impedance: |IOH|=IOL=4mA (min)
Balanced delay time: tpLHÝtpHL
Wide operating voltage range: VCC (opr) = 2 - 6 V.
Same pin connection as LSTTL (74LS138) and identical functions.
Package: DIP16
