Dual 2-to-4 Line Decoder
The TC74ACT139 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.
This device may be used as a level converter for interfacing
TTL or NMOS to High Speed CMOS. The inputs are compatible
with TTL, NMOS and CMOS output voltage levels.
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 = 5.5 ns (typ.) at VCC = 5 V
Low power dissipation: ICC = 8 µA (max) at Ta = 25°C
Compatible with TTL outputs: VIL = 0.8 V (max)
VIH = 2.0 V (min)
Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50
transmission lines.
Balanced propagation delays: tpLH ∼− tpHL
Pin and function compatible with 74F139
Note: xxxFN (JEDEC SOP) is not available in
Japan.
