DM74LS374N DATASHEET PDF

These 8-bit registers feature totem-pole 3-STATE outputs designed specifically for driving highly-capacitive or relatively low-impedance loads. The high-impedance state and increased high-logic level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for interface or pull-up components. When the enable is taken LOW the output will be latched at the level of the data that was set up. On the positive transition of the clock, the Q outputs will be set to the logic states that were set up at the D inputs. A buffered output control input can be used to place the eight outputs in either a normal logic state HIGH or LOW logic levels or a high-impedance state. In the high-impedance state the outputs neither load nor drive the bus lines significantly.

At an output "1" level of 2. On the other hand, the output "1" level of 74LS latch does not go to Vqc without an external pull-up resistor. In order to better approximate the COP output characteristics, add a 74C buffer to the output of the 74LS , thus. Upon power up, the K74CF will stabilize with the last output state valid before power down.

The non-volatile storage and recall. The timing of D port data is then ,. Using the set-up as shown in Figure 4, at an output "0 " level of 0.

At an output " 1" level of 2. On the other hand, the output " 1" level of 74LS latch does not go to Vcc , , add a 74C buffer to the output of the 74LS , thus emulat ing an open drain D output A pull-up. On the positive transition of the clock, the Q , established. OK, Thanks We use Cookies to give you best experience on our website.
