5V ECL 6-Bit Universal
Up/Down Counter
Description
cascadable universal counter. The device generates a look-ahead-carry
output and accepts a look-ahead-carry input. These two features allow
for the cascading of multiple E136’s for wider bit width counters that
operate at very nearly the same frequency as the stand alone counter.
before the E136 reaches terminal count. The COUT output will pulse
LOW for one clock cycle when the counter reaches terminal count.
For more information on utilizing the look-ahead-carry features of the
device please refer to the applications section of this data sheet. The
differential COUT output facilitates the E136’s use in programmable
divider and self-stopping counter applications.
carry−out and look-ahead-carry−out signals are registered on chip.
where the carry out signals are merely gated. Because of this
architecture there are some minor functional differences between the
E136 and H136 counters. The user, regardless of familiarity with the
H136, should read this data sheet carefully. Note specifically (see
logic diagram) the operation of the carry out outputs and the
look-ahead-carry in input when utilizing the master reset.
pull−down resistor. The master reset is an asynchronous signal which
when asserted will force the Q outputs LOW.
properly, in fact if these outputs will not be used in a system it is
recommended to save power and minimize noise that they be left
open. This practice will minimize switching noise which can reduce
the maximum count frequency of the device or significantly reduce
margins against other noise in the system.
