SN54/74LS175 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. • • • • • • QUAD D FLIP-FLOP LOW POWER SCHOTTKY Edge-Triggered D-Type Inputs Buffered-Positive Edge-Triggered Clock Clock to Output Delays of 30 ns Asynchronous Common Reset True and Complement Output Input Clamp Diodes Limit High Speed Termination Effects J SUFFIX CERAMIC CASE 620-09 CONNECTION DIAGRAM DIP (TOP VIEW) 16 1 NOTE: The Flatpak version has the same pinouts (Connection Diagram) as the Dual In-Line Package.

The LS175 is useful for general logic applications where a common Master Reset and Clock are acceptable. 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.

Figure 1. Clock to Output Delays, Clock Pulse Width, Frequency, Setup and Hold Times Data to Clock Figure 2. Master Reset to Output Delay, Master Reset Pulse Width, and Master Reset Recovery Time DEFINITIONS OF TERMS SETUP TIME (ts) — is defined as the minimum time required for the correct logic level to be present at the logic input prior to the clock transition from LOW to HIGH in order to be recognized and transferred to the outputs. HOLD TIME (th) — is defined as the minimum time following the clock transition from LOW to HIGH that the logic level must be maintained at the input in order to ensure continued recog- nition. A negative HOLD TIME indicates that the correct logic level may be released prior to the clock transition from LOW to HIGH and still be recognized. RECOVERY TIME (trec) — is defined as the minimum time required between the end of the reset pulse and the clock transition from LOW to HIGH in order to recognize and transfer HIGH Data to the Q outputs.
