1-of-10 decoder (3-State)
74F537
DESCRIPTION
PIN CONFIGURATION
The 74F537 is a one-of-ten decoder/demultiplexer with four active
High BCD inputs and ten mutually exclusive outputs. A Polarity
control (P) input determines whether the outputs are active Low or
active High. The 74F537 has 3-State outputs and a High signal on
the Output Enables (OE) input forces all outputs to the high
impedance state. Two input Enables, active High (E1) and active
Low (E0), are available for demultiplexing data to the selected
output in either non-inverted or inverted form. Input codes greater
than BCD nine causes all outputs to go to the inactive state (i.e.,
same polarity as the P input).

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value under the recommended operating conditions for the applicable type.
2. All typical values are at V = 5V, T = 25°C.

3. Not more than one output should be shorted at a time. For testing I , the use of high-speed test apparatus and/or sample-and-hold
OS
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I should be performed last.
