Product Introduction

Overview

The 74AC16373DL is a 16-bit transparent D-type latch with 3-state outputs, manufactured by Texas Instruments. This component is designed to drive high-capacitance or relatively low-impedance loads, making it ideal for applications such as buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be configured as two 8-bit latches or a single 16-bit latch. The device features a latch enable (LE) input that allows the Q outputs to follow the data (D) inputs when high, and latches the data when low. The buffered output enable (OE) input places the outputs in a high-impedance state, enabling bus driving without the need for interface or pull-up components. The 74AC16373DL is available in a 48-pin SSOP (Shrink Small Outline Package) and operates within a temperature range of -40°C to 85°C.

Q & A

1. What is the function of the latch enable (LE) input?

The latch enable (LE) input controls whether the Q outputs follow the data (D) inputs (when high) or latch the data (when low).

2. Can the 74AC16373DL be used as two separate 8-bit latches?

Yes, the device can be configured as two 8-bit latches or a single 16-bit latch.

3. What is the purpose of the output enable (OE) input?

The output enable (OE) input places the outputs in a high-impedance state, allowing bus driving without additional components.

4. What is the operating voltage range of the 74AC16373DL?

The device operates within a voltage range of 2V to 6V.

5. What is the temperature range for the 74AC16373DL?

It operates within an industrial temperature range of -40°C to 85°C.

6. What package is the 74AC16373DL available in?

It is available in a 48-pin SSOP (Shrink Small Outline Package).

7. What is the maximum propagation delay of the 74AC16373DL?

The maximum propagation delay is 5.5 ns at a 5V supply.

8. Is the 74AC16373DL suitable for high-speed applications?

Yes, its low propagation delay and 3-state outputs make it suitable for high-speed data transfer.

9. Can the 74AC16373DL drive high-capacitance loads?

Yes, it is designed to drive high-capacitance or relatively low-impedance loads.

10. What are the typical applications of the 74AC16373DL?

Typical applications include buffer registers, I/O ports, bidirectional bus drivers, and working registers.
