HT1628 datasheet led driver

Description

HT1628 is an LED Controller driven on a 1/7 to 1/8 duty factor. Eleven segment output lines, six grid output lines, 1 segment/grid output lines, one display memory, control circuit, key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for a single chip microcomputer. Serial data is fed to HT168 via four-line serial interface.

74ALVCH162244DGG datasheet

 

Description

The 74ALVCH162244 is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.

The IC is a 16-bit non-inverting buffer/line driver with 3-State outputs. The device can be used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The 3-State outputs are controlled by the output enable inputs 1OEand 2OE. A HIGH on nOEcauses the outputs to assume a high impedance OFF-state. The 74ALVCH162244 is designed with 30Ω series resistors in both HIGH and LOW output states.

The deivces has active bus hold circuitry which is provided to hold unused or floating data inputs at a valid logic level. This feature eliminates the need for external pull-up or pull-down resistors.

 

Features

1. Wide supply voltage range of 1.2V to 3.6V

2. Complies with JEDEC standard no. 8-1A

3. CMOS low power consumption

4. MULTIBYTETM flow-through standard pin-out architecture

5. Low inductance multiple VCC and ground pins for minimum noise and ground bounce

6. Direct interface with TTL levels

7. Bus hold on all data inputs
