PC74HC86TD PC74HC86TD PC74HC86TD Datasheet A page write is initiated the same way as a byte write, but the master does not send a stop condition after the first byte. Instead, after the slave has received the data byte, the master can send up to seven more bytes using the same nine-clock sequence. The master must terminate the write cycle with a stop condition or the data clocked into the DS1852 will not be latched into permanent memory. PC74HC86TD PC74HC86TD PC74HC86TD Price Error in write or read operation Within its life time, additional invalid blocks may develop with NAND Flash memory. Refer to the qualification report for the actual data.The following possible failure modes should be considered to implement a highly reliable system. In the case of status read fail- ure after erase or program, block replacement should be done. Because program status fail during a page program does not affect the data of the other pages in the same block, block replacement can be executed with a page-sized buffer by finding an erased empty block and reprogramming the current target data and copying the rest of the replaced block.To improve the efficiency of mem- ory space, it is recommended that the read or verification failure due to single bit error be reclaimed by ECC without any block replacement. The said additional block failure rate does not include those reclaimed blocks. PC74HC86TD PC74HC86TD PC74HC86TD on stock NOTES: 1. All typical values are at Vcc = 2.5V and Tamb = 25YC. 2. This is the increase in supply current for each input at the specified voltage level other than Vcc or GND 3. This parameter is valid for any Vcc between OV and l.2V with a transition time of up t0 10msec. From Vcc = 1.2V to Vcc = 2.5V + 0.2V a transition time of 100ffsec is permitted. This parameter is valid for Tamb = 25IC only. 4. Unused pins at Vcc or GND. 5. ICCZ is measured with outputs pulled up to Vcc or pulled down to ground. 6. Not guaranteed. AppLications .
