Overview
SN74LS90
DECADE COUNTER;
DIVIDE-BY-TWELVE
COUNTER;
4-BIT BINARY COUNTER
The SN54 / 74LS90, SN54 / 74LS92 and SN54 / 74LS93 are high-speed 4-bit ripple type counters partitioned into two sections.
Each counter has a divide-by-two section and either a divide-by-five (LS90), divide-by-six (LS92) or divide-by-eight (LS93) section which are triggered by a HIGH-to-LOW transition on the clock inputs.
Each section can be used separately or tied together (Q to CP) to form BCD, bi-quinary, modulo-12, or modulo-16 counters.
All of the counters have a 2-input gated Master Reset (Clear), and the LS90 also has a 2-input gated Master Set (Preset 9).
