FLIP FLOPS


Download File 1. DM74LS74A — Dual Positive-Edge-Triggered D Flip-Flops

This device contains two independent positive-edge-triggered D flip-flops with complementary outputs. The information on the D input is accepted by the flip-flops on the positive going edge of the clock pulse. The triggering occurs at a voltage level and is not directly related to the transition time of the rising edge of the clock.

The data on the D input may be changed while the clock is LOW or HIGH without affecting the outputs as long as the data setup and hold times are not violated. A low logic level on the preset or clear inputs will set or reset the outputs regardless of the logic levels of the other inputs.

The MC74HC574A is identical in pinout to the LS574. The device inputs are compatible with standard CMOS outputs; with pull-up resistors, they are compatible with LSTTL outputs.

The MM74HCT573 octal D-type latches and MM74HCT574 octal D-type flip-flop advanced silicon-gate CMOS technology, which provides the inherent benefits of low power consumption and wide power supply range, but are LS-TTL input and output characteristic and pin-out compatible.

The 3-STATE outputs are capable of driving 15 LS-TTL loads. All inputs are protected from damage due to static discharge by internal diodes to VCC and ground.


Download File 4. SN74LS377 — Octal D Flip-Flop with Enable; HEX D Flip-Flop with Enable; 4-Bit D Flip-Flop with Enable

The SN54/74LS377 is an 8-bit register built using advanced Low Power Schottky technology. This register consists of eight D-type flip-flops with a buffered common clock and a buffered common clock enable.

The SN54/74LS378 is a 6-Bit Register with a buffered common enable. This device is similar to the SN54/74LS174, but with common Enable rather than common Master Reset.

The SN54/74LS379 is a 4-Bit Register with buffered common Enable. This device is similar to the SN54/74LS175 but features the common Enable rather then common Master Reset.
