MC14556BDR2
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. Diode Protection on All Inputs Active High or Active Low Outputs Expandable Supply Voltage Range = 3.0 Vdc to 18 Vdc All Outputs Buffered Capable of Driving Two Low–Power TTL Loads or One Low–Power
Schottky TTL Load Over the Rated Temperature Range
MAXIMUM RATINGS (Voltages Referenced to VSS) (Note 2.) Maximum Ratings are those values beyond which damage to the device
may occur. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/ C From 65 C To 125C
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.
