Part Number: SN74AHC245Q Other Parts Discussed in Thread: SN74AHC245-Q1 , Hi team
In addition to the package option, could you help give the difference between SN74AHC245Q and SN74AHC245-Q1?
Thank you.
These signals violate the setup and hold times specified in section 7.6 of the datasheet.
What is the purpose of using a flip-flop in this circuit? Why are you mentioning the '245 transceiver? It's possible that that device, or a transparent latch like…
Hi Alan,
The group responsible for the SN74AHC245 device reassigned this thread back to me.
A discrete solution for this is a bit tricky. If you want to discuss this further, we can do it offline.

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 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…
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…
Part Number: TXB0104 Other Parts Discussed in Thread: SN74AHC245 Tool/software: I use TXB0104 as a buffer for amplifying signals form TFP2 programator. Power supplied Vcca=Vccb=3V3. For some reason TXRX signal HI level from TFP2 side is being reduced…
1. Testing is expensive; I guess there have been no customers for this so far.
2. 2× SN74AHC244-EP or SN74AHC245-EP in the TSSOP package has 2 × 6.5 mm × 6.4 mm; 2× SN74LVC8T245-EP in the VQFN package has 2 × 5.5 mm × 3.5 mm; SN74LVCH16T245-EP in the…
Part Number: SN74AUP1G125 Other Parts Discussed in Thread: SN74LV245A , SN74AHC245 , SN74LXC1T45 Hi
Could you help suggest suitable product s
bidirectional single channel buffer
Vin max: 5.5V IOL: 40mA max.
The absolute maximum ratings forbid any I/O voltage exceeding the supply voltage, unless the current is limited to 20 mA.
Just use a device with overvoltage-tolerant inputs, e.g., SN74AHC245.
