Description and Introduction

OCTAL D-TYPE LATCH WITH 3-STATE OUTPUT The TC74HCT573AF is a high-speed CMOS octal D-type latch manufactured by Toshiba. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Logic Family:** HCT (High-Speed CMOS, TTL compatible)
- **Number of Bits:** 8 (Octal)
- **Latch Type:** Transparent (3-state output)
- **Supply Voltage Range:** 4.5V to 5.5V
- **High-Level Input Voltage (Min):** 2.0V
- **Low-Level Input Voltage (Max):** 0.8V
- **Output Current (High/Low):** ±6mA
- **Propagation Delay:** 17ns (typical at 5V)
- **Operating Temperature Range:** -40°C to +85°C
- **Package Type:** SOP-20 (Small Outline Package, 20-pin)

### **Descriptions:**
- The TC74HCT573AF is an octal transparent latch with 3-state outputs, designed for bus interface applications.
- It features a latch enable (LE) input and an output enable (OE) input for controlling data flow.
- When LE is high, the input data is transferred to the outputs. When LE is low, the outputs retain their last state.
- The OE pin, when high, places the outputs in a high-impedance state, allowing multiple devices to share a bus.

### **Features:**
- **TTL-Compatible Inputs:** Works with both CMOS and TTL logic levels.
- **3-State Outputs:** Allows bus-oriented operation.
- **High-Speed Operation:** Suitable for high-performance applications.
- **Low Power Consumption:** CMOS technology ensures low power dissipation.
- **Wide Operating Voltage Range:** Supports standard 5V systems.

This information is based on Toshiba's datasheet for the TC74HCT573AF.
