74F537 Datasheet, PDF (1/5 Pages) NXP Semiconductors – 1-of-10 decoder 3-State

Philips Semiconductors
1-of-10 decoder (3-State)
Product specification
74F537
DESCRIPTION
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).
