SN74AUP1T08DCKR屬于集成電路（IC）的門反相器。由美國德州儀器公司制造生產的SN74AUP1T08DCKR門和反相器邏輯柵極和逆變器系列中的產品對單個邏輯信號執(zhí)行基本邏輯運算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲信息，不會對提供給其輸入的信號立即做出響應。雖然早就被集成電路實施形式所取代，以用于實現(xiàn)復雜功能，但分立柵極仍可在僅需要非常簡單邏輯功能的情況下使用。

2 Description

The SN74AUP1T08 performs the Boolean function

Y = A ? B or Y = A + B with designation for logic-level

translation applications with output referenced to

supply VCC.

AUP technology is the industry's lowest-power logic

technology designed for use in extending battery-life

in operating. All input levels that accept 1.8-V

LVCMOS signals, while operating from either a single

3.3-V or 2.5-V VCC supply. This product also

maintains excellent signal integrity (see Figure 5-1

and Figure 5-2).

The wide VCC range of 2.3 V to 3.6 V allows the

possibility of switching output level to connect to

external controllers or processors.

Schmitt-trigger inputs (ΔVT = 210 mV between

positive and negative input transitions) offer improved

noise immunity during switching transitions, which is

especially useful on analog mixed-mode designs.

Schmitt-trigger inputs reject input noise, ensure

integrity of output signals, and allow for slow input

signal transition.

Ioff is a feature that allows for powered-down

conditions (VCC = 0 V) and is important in portable

and mobile applications. When VCC = 0 V, signals in

the range from 0 V to 3.6 V can be applied to the

inputs and outputs of the device. No damage occurs

to the device under these conditions.

The SN74AUP1T08 is designed with optimized

current-drive capability of 4 mA to reduce line

reflections, overshoot, and undershoot caused by

high-drive outputs.
