SN54LS175
QUAD D FLIP-FLOP
The LSTTL / MSI SN54 / 74LS175 is a high speed Quad D Flip-Flop. The
device is useful for general flip-flop requirements where clock and clear inputs
are common. The information on the D inputs is stored during the LOW to
HIGH clock transition. Both true and complemented outputs of each flip-flop
are provided. A Master Reset input resets all flip-flops, independent of the
Clock or D inputs, when LOW.
The LS175 is fabricated with the Schottky barrier diode process for high
speed and is completely compatible with all Motorola TTL families.

FUNCTIONAL DESCRIPTION
The LS175 consists of four edge-triggered D flip-flops with
individual D inputs and Q and Q outputs. The Clock and
Master Reset are common. The four flip-flops will store the
state of their individual D inputs on the LOW to HIGH Clock
(CP) transition, causing individual Q and Q outputs to follow. A
LOW input on the Master Reset (MR) will force all Q outputs
LOW and Q outputs HIGH independent of Clock or Data
inputs.
The LS175 is useful for general logic applications where a
common Master Reset and Clock are acceptable.
