ON MC14555B Dual binary to 1-of-4 decoder/demultiplexer Datasheet

MC14555B, MC14556B
Dual Binary to 1-of-4
Decoder/Demultiplexer
The MC14555B and MC14556B are constructed with
complementary MOS (CMOS) enhancement mode devices. Each
Decoder/Demultiplexer has two select inputs (A and B), an active low
Enable input (E), and four mutually exclusive outputs (Q0, Q1, Q2,
Q3). The MC14555B has the selected output go to the “high” state,
and the MC14556B has the selected output go to the “low” state.
Expanded decoding such as binary−to−hexadecimal (1−of−16), etc.,
can be achieved by using other MC14555B or MC14556B devices.
Applications include code conversion, address decoding, memory
selection control, and demultiplexing (using the Enable input as a data
input) in digital data transmission systems.

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Temperature Derating: “D/DW” Packages: –7.0 mW/°C From 65°C To 125°C
This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
high−impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS ≤ (Vin or Vout) ≤ VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
2. Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
3. The formulas given are for the typical characteristics only at 25°C.
4. To calculate total supply current at loads other than 50 pF: IT(CL) = IT(50 pF) + (CL – 50) Vfk where: IT is in mA (per package), CL in pF,
V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.002.
