74HCT Series 5.5V Surface Mount 3-State Octal Buffer/Line Driver - TSSOP-20
The 74HC595PW is a 8-bit serial-in/serial or parallel-out Shift Register with a storage register and 3-state outputs. Both the shift and storage register have separate clocks. The device features a serial input (DS) and a serial output (Q7S) to enable cascading and an asynchronous reset MR\ input. A low on MR\ will reset the shift register. Data is shifted on the low-to-high transitions of the SHCP input. The data in the shift register is transferred to the storage register on a low-to-high transition of the STCP input. If both clocks are connected together, the shift register will always be one clock pulse ahead of the storage register. Data in the storage register appears at the output whenever the OE\ is low. A high on OE\ causes the outputs to assume a high-impedance OFF-state. Operation of the OE\ input does not affect the state of the registers. Inputs include clamp diodes.
This MC74HCT244ADTR2G buffer and line driver from ON Semiconductor is used to amplify an analog or digital signal by driving the input to the transmission line. With a 3-state output, this is power management at its best. This line driver has a minimum operating temperature of -55 °C and a maximum of 125 °C. This product will be shipped in tape and reel packaging to allow for quick mounting and safe delivery. It has 8 channels per chip. This non-inverting device has a typical operating supply voltage of 5 V. Its minimum operating supply voltage of 4.5 V, while its maximum is 5.5 V.
