ST6G3240
Dual supply level translator for dual memory cards
(mini SD/micro SD + managed NAND)
Features
High speed: tPD (A to B) = 5 ns at TA = 85 °C
with VCCA = 1.8 V, VCCBn = 3.0 V
Low power dissipation: ICCA = ICCBn = 5 µA
(max.) at TA = 85 °C
Balanced propagation delays: tPLH tPHL
Operating voltage range:
– VCCA (opr) = 1.4 to 3.6 V
– VCCBn (opr) = 1.4 to 3.6 V
B-side power supplies (VCCB1 and VCCB2) can
be different and separately controlled
Interchangeable voltage levels:
VCCA can either be greater than or less than
VCCBn
Low power mode:
when VCCBn is grounded or floating, there is
very low quiescent current on VCCA
Power down detection:
when either one of the B-side power supplies
(VCCB1 and VCCB2) is grounded or floating, the
corresponding port-n goes into high-Z state
automatically
Latch-up performance exceeds 500 mA
(JESD17)
ESD protection: 2 kV HBM
Integrated pull-up resistor and level translator

Description
The ST6G3240 is a dual supply low voltage
CMOS level translator supporting the dual
function of mini SD/micro SD card and managed
NAND memories. It is designed for use as an
interface between three systems using 3.3, 2.5
and 1.8 V respectively.
The ST6G3240 is capable of achieving high
speed operation and at the same time maintaining
low power dissipation.
While the A port is designed to track VCCA, the Bn
port (nCMD, nDAT, nCLK) is designed to track
VCCBn.
The device is intended for a two-way
asynchronous communication between data
buses.

It is required that VCC supply and ground pins are in close proximity, so as to allow for easy
capacitive coupling in application.
