The SN54 /74LS90, SN54/74LS92 and SN54/74LS93 are high-speed
4-bit ripple type counters partitioned into two sections. Each counter has a di-
vide-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 transi-
tion 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). Low Power Consumption... Typically 45 mW High Count Rates... Typically 42 MHz Choice of Counting Modes... BCD, Bi-Quinary, Divide-by-Twelve,
Binary Input Clamp Diodes Limit High Speed Termination Effects
PIN NAMES LOADING (Note a)

CP0 Clock (Active LOW going edge) Input to
÷2 Section
CP1 Clock (Active LOW going edge) Input to
÷5 Section (LS90), ÷6 Section (LS92)
CP1 Clock (Active LOW going edge) Input to
÷8 Section (LS93)
MR1, MR2 Master Reset (Clear) Inputs
MS1, MS2 Master Set (Preset-9, LS90) Inputs Output from ÷2 Section (Notes b & c)
Q1, Q2, Q3 Outputs from ÷5 (LS90), ÷6 (LS92),
÷8 (LS93) Sections (Note b)
NOTES:
a. 1 TTL Unit Load (U.L.) = 40 μA HIGH/1.6 mA LOW.
b. The Output LOW drive factor is 2.5 U.L. for Military, (54) and 5 U.L. for commercial (74)
b. Temperature Ranges.
c. The Q0 Outputs are guaranteed to drive the full fan-out plus the CP1 input of the device.
d. To insure proper operation the rise (tr) and fall time (tf) of the clock must be less than 100 ns.
