74HC40103PW规格书详情
1. General description
The 74HC40103 is an 8-bit synchronous down counter. It has control inputs for enabling
or disabling the clock (CP), for clearing the counter to its maximum count and for
presetting the counter either synchronously or asynchronously. In normal operation, the
counter is decremented by one count on each positive-going transition of the clock (CP).
Counting is inhibited when the terminal enable input (TE) is HIGH. The terminal count
output (TC) goes LOW when the count reaches zero if TE is LOW, and remains LOW for
one full clock period. When the synchronous preset enable input (PE) is LOW, data at the
jam input (P0 to P7) is clocked into the counter on the next positive-going clock transition
regardless of the state of TE. When the asynchronous preset enable input (PL) is LOW,
data at the jam input (P0 to P7) is asynchronously forced into the counter regardless of
the state of PE, TE, or CP. The jam inputs (P0 to P7) represent a single 8-bit binary word.
When the master reset input (MR) is LOW, the counter is asynchronously cleared to its
maximum count (decimal 255) regardless of the state of any other input. If all control
inputs except TE are HIGH at the time of zero count, the counters will jump to the
maximum count, giving a counting sequence of 256 clock pulses long. Device may be
cascaded using the TE input and the TC output, in either a synchronous or ripple mode.
Inputs include clamp diodes. This enables the use of current limiting resistors to interface
inputs to voltages in excess of VCC.
