TC74HC139AP/AF
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74HC139AP,TC74HC139AF
Dual 2-to-4 Line Decoder
The TC74HC139A is a high speed CMOS 2-to-4 LINE
DECODER/DEMULTIPLEXER fabricated with silicon gate
C2MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL 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 âHâ, 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 = 16 ns (typ.) at VCC = 5 V
⢠Low power dissipation: ICC = 4 μA (max) at Ta = 25°C
⢠High noise immunity: VNIH = VNIL = 28% VCC (min)
⢠Output drive capability: 10 LSTTL loads
⢠Symmetrical output impedance: |IOH| = IOL = 4 mA (min)
⢠Balanced propagation delays: tpLH â¼â tpHL
⢠Wide operating voltage range: VCC (opr) = 2~6 V
⢠Pin and function compatible with 74LS139
