202111014I : Modifications to NVT4557 and NVT4858 Data Sheet
NVT4557 Data Sheet * Changed 1.95 V to 1.98 V and 1.65 V to 1.62 V throughout the data sheet per customer request for 1.8V +/- 10% * Section 4 Order Information Corrected topside marking for NVT4557UK from "557" to "7" and orderable part number from "NTV4557UKJ" to "NTV4557UKAZ" with packing method dry pack (DP). * Section 6.1 Pin Description Added text to make more clear only on 10 pin version there is an enable pin for the for the 9 pin version the enable pin is pulled to VCCA internally. * Section 9 Characteristics Table 7 revised as follows: – ICCA: revised the conditions adding "=VCCA" after "IO_HOST" – ICCB: revised the conditions adding "VCCB = 3.6 V" corrected operating mode Typ value from "20" to "300" and Max value from "30" to "350". Corrected the Quiescent current mode Max value from “4.2” to “10” uA. * Section 9 Characteristics Figure 8 – split graph - ICCA in uA in Figure 8 and moved ICCB in mA to new Figure 9 to make graph more readable. * Section 9 Characteristics Table 8 revised as follows; – VCCB_DIS: revised Max from 1.4V to 0.8V – ΔVCCBen: removed row. – VOH: revised the three Min values from 0.75 x VCCB to 0.8 x VCCB and revised the the IO_Host condition from -10 μA to -8 μA to better match application requirements. – Rpd: removed "EN = 0" from the condition and added footnote that the EN pin is not featured on the 9 pin version and is pulled internally to VCCA. NVT4858 Data Sheet * Changed 1.95 V to 1.98 V and 1.65 V to 1.62 V throughout the data sheet per customer request for 1.8V +/- 10% * Table 11 - Deleted Automatic enable feature: VCCB hysteresis voltage * Table 13. - Added skew information for SD card level translator skew - NVT4858HK (QFN) and NVT4858UK (WLCSP)
