NE-VA30 series are the thermal printheads developed for high-speed / high-resolution printing for the market of bar-code printer & scale-printer, based on "step-free" structure These printheads realize ultra-highspeed printing with long life & high reliability.

The ALVC162835 low voltage 18-bit universal bus driver combines D-type latches and D-type flip-flops to allow data flow in transparent, latched and clocked modes.

Data flow is controlled by output-enable (OE), latch-enable (LE), and clock (CLK) inputs. The device operates in Transparent Mode when LE is held HIGH. The device operates in clocked mode when LE is LOW and CLK is toggled.Data transfers from the Inputs (In) to Outputs (On) on a Positive Edge Transition of the Clock. When OE is LOW, the output data is enabled. When OE is HIGH the output port is in a high impedance state.

The ALVC162835 is designed with 26Ω series resistors in the outputs. This design reduces noise in applications such as memory address drivers, clock drivers, and bus transceivers/ transmitters.

The 74ALVC162835 is designed for low voltage (1.65V to 3.6V) VCC applications with I/O capability up to 3.6V. The 74ALVC162835 is fabricated with an advanced CMOS technology to achieve high speed operation while maintaining low CMOS power dissipation.

The TC7MH573FK is an advanced high speed CMOS octal latch with 3-state output fabricated with silicon gate C²MOS
technology.

It achieves the high speed operation similar to equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation.

This 8 bit D-type latch is controlled by a latch enable input (LE) and a output enable input (OE ).

When the OE input is high, the eight outputs are in a high impedance state.

An input protection circuit ensures that 0 to 7 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
