Other Parts Discussed in Thread: SN74LVC2G132 I tried to use PSpice for TI to simulate the power ONOFF logic with SN74LVC2G132. Schematic and simulation output are below.
Why the voltage at U2 input A can only reach to 0.5V? I checked the PSpice model…
Hi Thomas,
Thank you for your reply!
The reference design uses a NAND gate with Schmitt trigger. The current customer design does use a device without Schmitt trigger input (SN74LV00APWR). We think this may be the main reason for the functional abnormality…

Hi,
I follow the circuit as shown in the following diagram to control the shutdown pin of an LDO with a tactile switch.
Vcc =5Volts. The circuit works as expected BUT I'm facing…
An alternative solution would be to use a set/reset latch. Integrated devices like the SN74LS279A are available only in a quad package, but you could construct one from two NAND gates (e.g., SN74LVC2G132):
Use an R-C circuit to generate a low pulse on…
Hi Eric,
Thanks for you reply!
Can i replace the SN74LVC2G132 with SN74LVC2G14？And i can change the RC value to get the same delay time.
Regards,
Kevin
Whatever happens on CLK does not matter for initialization, because the initial state is unknown to begin with . You always need a low pulse on PRE .
During power up, there is no initialization time; after the supply has reached the minimum allowed voltage…
Other Parts Discussed in Thread: SN74LVC2G132 Team,
can you please help in crossing the NC7WZ132L8X?
A direct replacement part would be beneficial but not strictly required.
Thanks
Other Parts Discussed in Thread: SN74LVC1G97 , SN74LVC2G132 , LSF0102 , SN74LVC1G17-Q1 I have a 20MHz Reference Clock application which has 1.8V output from LVCMOS FPGA I/O and requires conversion to TTL level output. TTL level is driving into a 50 ohm coax…
