ST6G3240
Dual supply level translator for dual memory cards
(mini SD/micro SD + managed NAND)
Features
■ High speed: t_PD (A to B) = 5 ns at T_A = 85 °C
with V_CCA = 1.8 V, V_CCBn = 3.0 V
■ Low power dissipation: I_CCA = I_CCBn = 5 µA
(max.) at T_A = 85 °C
■ Balanced propagation delays: t_PLH ≈ t_PHL
■ Operating voltage range:
– V_CCA (opr) = 1.4 to 3.6 V
– V_CCBn (opr) = 1.4 to 3.6 V
■ B-side power supplies (V_CCB1 and V_CCB2) can
be different and separately controlled
■ Interchangeable voltage levels:
V_CCA can either be greater than or less than
V_CCBn
■ Low power mode:
when V_CCBn is grounded or floating, there is
very low quiescent current on V_CCA
■ Power down detection:
when either one of the B-side power supplies
(V_CCB1 and V_CCB2) 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
on the MS_Insert pin
■ Integrated pull-up resistor for card-detect pin

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 V_CCA, the Bn
port (nCMD, nDAT, nCLK) is designed to track
V_CCBn.
The device is intended for a two-way
asynchronous communication between data
buses.
