SN74LV8153QPWRQ1屬于集成電路（IC）的移位寄存器。由美國(guó)德州儀器公司制造生產(chǎn)的SN74LV8153QPWRQ1移位寄存器移位寄存器是低級(jí)邏輯器件，通常用于在串行和并行方式之間轉(zhuǎn)換數(shù)字邏輯信號(hào)形式的數(shù)據(jù)，或在數(shù)字字內(nèi)移動(dòng)數(shù)據(jù)位的位置。移位寄存器通常使用集成到一個(gè)設(shè)備中的一組觸發(fā)器來(lái)實(shí)現(xiàn)，常用于集成度更高的邏輯器件，但仍可用于 I/O 擴(kuò)展等應(yīng)用，在這些應(yīng)用中離散形式的函數(shù)可能會(huì)非常有用。

DESCRIPTION

The SN74LV8153 is a serial-to-parallel data converter. It

accepts serial input data and outputs 8-bit parallel data.

The automatic data-rate detection feature of the

SN74LV8153 eliminates the need for an external oscillator

and helps with cost and board real-estate savings.

The OUTSEL pin is used to choose between open

collector and push-pull outputs. The open-collector option

is suitable when this device is used in applications such as

LED interface, where high drive current is required. SOUT

is the output that acknowledges reception of the serial

data.

To ensure the high-impedance state during power up or

power down, OE should be tied to VCC1 through a pullup

resistor; the minimum value of the resistor is determined

by the current-sinking capability of the driver.
