74AHC139; 74AHCT139
Dual 2-to-4 line decoder/demultiplexer
Rev. 02 -- 9 May 2008 Product data sheet
1. General description
The 74AHC139; 74AHCT139 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard No. 7-A. The 74AHC139; 74AHCT139 is a high-speed, dual 2-to-4 line decoder/demultiplexer. This device has two independent decoders, each accepting two binary weighted inputs (nA0 and nA1) and providing four mutually exclusive active LOW outputs (nY0 to nY3). Each decoder has an active LOW enable input (nE). When nE is HIGH, every output is forced HIGH. The enable input can be used as the data input for a 1-to-4 demultiplexer application. The 74AHC139; 74AHCT139 is identical to the HEF4556 of the HE4000B family.

Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V). tpd is the same as tPLH and tPHL. CPD is used to determine the dynamic power dissipation (PD in W). PD = CPD x VCC2 x fi x N + (CL x VCC2 x fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in V; N = number of inputs switching; (CL x VCC2 x fo) = sum of the outputs.
