SN54LVT245B and SN74LVT245B are 3.3-V ABT octal bus transceivers with 3-state outputs. They are designed using state-of-the-art BiCMOS technology for 3.3-V operation and low static-power dissipation. These devices support mixed-mode signal operation with 5-V input and output voltages using 3.3-V VCC. They also support unregulated battery operation down to 2.7 V. The typical VOLP (output ground bounce) is less than 0.8 V at VCC = 3.3 V and TA = 25°C. They provide Ioff and power-up 3-state support for hot insertion. The latch-up performance exceeds 100 mA per JESD 78, Class II. The ESD protection exceeds JESD 22 specifications, with a 2000-V human-body model (A114-A), 200-V machine model (A115-A), and 1000-V charged-device model (C101). Package options include plastic small-outline (DW), shrink small-outline (DB), and thin shrink small-outline (PW) packages, ceramic chip carriers (FK), ceramic flat (W) packages, and ceramic (J) DIPs.

The AM26LV32 is a BiCMOS, quadruple, differential line receiver with 3-state outputs, designed to be similar to TIA/EIA-422-B and ITU Recommendation V.11 receivers, but with a reduced common-mode voltage range due to reduced supply voltage. The device is optimized for balanced bus transmission at switching rates up to 32 MHz. The enable function is common to all four receivers and offers a choice of active-high or active-low inputs. The 3-state outputs permit direct connection to a bus-organized system. Each device features receiver high input impedance and input hysteresis for increased noise immunity, and input sensitivity of ±200 mV over a common-mode input voltage range from −0.3 V to 5.5 V. When the inputs are open circuited, the outputs are in the high logic state. This device is designed using the Texas Instruments (TI) proprietary LinIMPACT-C60 technology, facilitating ultra-low power dissipation.

The TPS4030x is a family of cost-optimized synchronous buck controllers that operate from 3-V to 20-V input. The controller implements a voltage-mode control architecture with input-voltage feed-forward compensation that responds instantly to input voltage change. The switching frequency is fixed at 300 KHz, 600 KHz or 1.2 MHz. Frequency Spread Spectrum feature adds dither to the switching frequency, significantly reducing the peak EMI noise and making it much easier to comply with EMI standards. The TPS4030x has good EMI performance and can be used in various applications such as POL modules, printers, digital TVs and telecommunications.
