Level translators need no direction
control
Bidirectional voltage-level translation devices improve connectivity between next-generation processors and peripheral devices.
Texas Instruments has released two bidirectional voltage-level translation devices, the TXB0104 and TXS0104E, that improve connectivity between next-generation processors and peripheral devices Eliminating the requirement for direction control signals used by traditional voltage-level translation devices, designers are able to decrease the complexity of control software and save valuable GPIOs on core processors

RF platform brings three radios together
Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
The TXB0104, a 4bit bidirectional voltage-level translator, provides universal low-voltage bidirectional translation between any of the 1.2, 1.5, 1.8, 2.5, 3.3 and 5V nodes.
VCCA accepts any supply voltage from 1.2 to 3.6V.
The B port is designed to track VCCB.
VCCB accepts any supply voltage from 1.65 to 5.5V.
This device is suitable for applications such as SD card interface via SD 1bit mode or SPI mode.
For open drain applications, such as I2C or MMC card interface (initialisation mode), TI's new TXS0104E, 4bit bidirectional voltage-level translator, contains integrated pull-up resistors saving valuable board real estate and total system cost.
The TXS0104E uses two separate configurable power-supply rails.
The A port is designed to track VCCA.
VCCA accepts any supply voltage from 1.65 to 3.6V; VCCA must be less than or equal to VCCB.
The B port is designed to track VCCB.
VCCB accepts any supply voltage from 2.3 to 5.5V.
This allows for low-voltage bidirectional translation between any of the 1.8, 2.5, 3.3 and 5V voltage nodes.
The TXB0104 and TXS0104E are offered in traditional SOIC (D), TSSOP (PW) and QFN (RGY) packages, as well as the space saving 12-ball BGA (ZXU) package.
Both devices are available to sample in all package options.
Budgetary pricing for the TXB0104ZXUR is set at US $1.21 in quantities of 1000.
Budgetary pricing for the TXS0104EZXUR is set at $1.41 in quantities of 1000.
