Dual 2-to-4 Line Decoder
The TC74AC139 is an advanced high speed CMOS 2-to-4 LINE
DECODER fabricated with silicon gate and double-layer metal
wiring C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
The active low enable input can be used for gating or it can be
used as a data input for demultiplexing applications.
When the enable input is held “H”, all four outputs are fixed at
a high logic level independent of the other inputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
• High speed: tpd = 5.9 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 8 µA (max) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28% VCC (min)
• Symmetrical output impedance:
|IOH| = IOL = 24 mA (min) Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: tpLH ∼− tpHL DataSheet4U.com
• Wide operating voltage range: VCC (opr) = 2 V to 5.5 V
• Pin and function compatible with 74F139
Note: xxxFN (JEDEC SOP) is not available in
Japan.
