Part Number: SN74AHC245 Hi team,
I have some questions on the schematic of SN74AHC245PWR datasheet.
Are there any diodes inside of IC between input and power?
Are there any protestation inside of IC? Or need to restrict the input current?
If none of …
Part Number: SN74AHC245 Please tell us the cause of the power supply potential rise.
An experiment was performed using 74AHC245 under the following conditions. VCC = DIR = 3.3V. / OE = 0V. A1 = 5V.
The stabilized power supply used for the IC power supply…

Hello,
My customer would like to know if we have any existing AEC-Q100 transceivers that could implement the equivalent functionality of TI's P82B96…
Part Number: SN74AHC245 What is the input impedance of SN74AHC245QPWR? When I put an RC filter(100ohm+1nF) at the input. The high level and low level of input signal are 5V and 0V. But i can only see 4.1V after the resistor. So i am wondering if it is…
Part Number: SN74AHC245 Hi,
I bought some pieces of SN74AHC245DWR, and found the pins of them are all black.
I want to know if the pins are black or silver, if silver, why the pins are black? Is it oxidizing?
Looking forward to your reply, thank you.
Part Number: SN74AHC245 Hi Team,
On my customer's system, the SN74AHC245 direction (DIR) pin is controlled by a R/nW signal (logic 1 selects A->B) and side A of the transceiver is connected to a bus, which connects to circuit boards and components that…

Could you help suggest suitable product s
bidirectional single channel buffer
Vin max: 5.5V IOL: 40mA max.
That depends on what characteristics you need, especially drive strength. Some possible alternatives are SN74AHC245-EP, SN74AC245-EP, or SN74ABT245B-EP.
When you go beyond the recommended operating conditions, the electrical characteristics are not longer guaranteed.
For a 5 V supply, use a 5 V device like the SN74AHC245 or SN74LV245A.
3.3 V signals do not work with normal 5 V CMOS inputs. For those,…
