Octal Transparent D-Type Latches With 3-State Outputs The SN74AC533DBR is a digital integrated circuit (IC) manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:
### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)
- **Part Number:** SN74AC533DBR
- **Type:** Octal Transparent D-Type Latch with 3-State Outputs
- **Technology:** Advanced CMOS (AC)
- **Supply Voltage Range:** 2 V to 6 V
- **Operating Temperature Range:** -40°C to +85°C
- **Package:** SSOP (Shrink Small Outline Package) - 20 pins
- **Output Type:** 3-State (High-Impedance, High, Low)
- **Latch Type:** Transparent (Data passes through when latch enable is active)
- **Number of Bits:** 8 (Octal)
- **Propagation Delay:** Typically 7.5 ns at 5V
- **Input/Output Compatibility:** TTL-Compatible Inputs
### **Descriptions:**
- The SN74AC533DBR is an octal transparent latch with 3-state outputs, designed for bus interface applications.
- It features a latch enable (LE) input that, when high, allows data to pass through to the outputs. When LE is low, the outputs hold the last data present before the transition.
- The output enable (OE) input controls the 3-state outputs, allowing multiple devices to share a common bus.
### **Features:**
- **Octal D-Type Latch with 3-State Outputs**
- **Wide Operating Voltage Range (2V to 6V)**
- **Balanced Propagation Delays**
- **Low Power Consumption (CMOS Technology)**
- **Inputs Accept TTL Levels**
- **Bus-Structured Pinout**
- **ESD Protection Exceeds 2000 V (Per JESD 22-A114)**
- **Latch-Up Performance Exceeds 250 mA (Per JESD 78)**
