74HCT373 Octal transparent D-type latches

CD74HCT373 – High Speed CMOS Logic Octal Transparent Latches with 3-State Outputs

The ‘HCT373 devices are octal transparent D-type latches. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs are latched at the logic levels of the D inputs.

What it can do ?

This is like a Byte of Memory, A Byte means 8 Bits. A Bit Means one Input or Output Pin of an IC, Which understands Logic 1 is High and Logic 0 is Low.

The HCT works well with old TTL and CMOS families. This takes very less Power (battery lasts longer). It switches very fast (the computation is done faster). Its got good symmetrical output drive. Means Source and Sink both nice.

When you run out of ports I/O in your favorite uC, This guy will come to your rescue. Simple way is to Put four of this and Interconnect or Bus their Data inputs D0-D7. Then Connect this Bus to 8 Ports of our uC Chip. Enable the Output of all of them. Use 4 ports from your uC to latch each one with the data you want to be outputted. Now you have 8×4 32 Bits output. This comes at a small cost, the clock time, but negligible. In the same way you can enhance the Input ports, use the 373, the other way around with OE.

This all means more Keys, Sensors, Motors, Relays can be accommodated. By Multiplexing Matrix even more can be achieved. You can also expand Analog Inputs using Analog Multiplexers. Try CD4051 or even FETs.

Utility of Testing and Troubleshooting Tools

Utility of Testing and Troubleshooting Tools : The first thing in Electrical testing is the Continuity Tester, Then we use the Neon Mains Screwdriver, Then we need an Voltmeter or an Ammeter. In electronics we need a OhmMeter and LCR meter too.

Many times we cannot carry big or expensive test instruments to the field, so we have to have a troubleshooting tool kit. Continuity testers, Logic Probes, DMM, Clamp Meters etc..

Simple Test Equipment

It also is sometimes required to build a quick jig or fixture with electronics to troubleshoot, simulate a problem or to test the reliability or aging of components and systems. Here you need to be cost effective, fast and innovative; and build a simple system with available, affordable or procurable resources. Hence a bit of circuit design, firmware and software are essential skills for production engineering.
