Modeling Latches and Flip-flops - Xilinx
www.xilinx.comflip-flop can be viewed as a memory cell or a delay line. The active edge in a flip-flop could be rising or falling. The following figure shows rising (also called positive) edge triggered D flip-flop and falling (negative edge) triggered D flip-flop. The positive edge triggered D flip-flop can be modeled using behavioral modeling as shown below.

MC74HC74A - Dual D Flip-Flop with Set and Reset
www.onsemi.comDual D Flip-Flop with Set and Reset High−Performance Silicon−Gate CMOS The MC74HC74A is identical in pinout to the LS74. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This device consists of two D flip−flops with individual Set, Reset, and Clock inputs.
Lecture 6 Flip-Flop and Clock Design
courses.ece.ubc.caRequirements in Flip-Flop Design • Minimize FF overhead: small clk-q delay, tsetup, thold times • Minimize power – expensive packages and cooling systems – flops up to 20% of total power of high-performance systems • High driving capability – Typical flip-flop load in a 0.18 µm CMOS ranges from 50fF to

Dual D-type flip-flop
assets.nexperia.comDual D-type flip-flop Rev. 10 — 23 November 2021 Product data sheet 1. General description The HEF4013B is a dual D-type flip-flop with set and reset; positive-edge trigger. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VDD. 2. Features and benefits
Metastability - University of Southern California
www-classes.usc.edutypically described by four measurements of flip-flop performance — MTBF, T, To and tr. MTBF is the “mean-time-between-failure” of a flip-flop. where tr is metastability resolution time, maximum time the output can remain metastable without causing synchronizer failure. …
