Part Number: 74LV245

Function: Octal Bus Transceiver (3-State)

Package: DIP, SO, SSOP, TSSOP 20 pin Type

Manufacturer: NXP Semiconductors.

Pinouts:

Description

The 74LV245 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC245 and 74HCT245.

The device is an octal transceiver with non-inverting 3-state bus compatible outputs in both send and receive directions. A send/receive (DIR) input controls direction, and an output enable (OE) input makes easy cascading possible. PinOE controls the outputs so that the buses are effectively isolated.

Features

1. Wide operating voltage: 1.0 V to 5.5 V

2. Optimized for low voltage applications: 1.0 V to 3.6 V

3. Accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V

4. Typical output ground bounce < 0.8 V at VCC = 3.3 V and Tamb = 25 °C

5. Typical HIGH-level output voltage (VOH) undershoot: > 2 V at VCC = 3.3 V and Tamb = 25 °C

Part Number: SN75176

Function: Differential Bus Transceiver

Package: DIP, SOIC 8 Pin Type

Manufacturer: Texas Instruments

Description

The SN75176 differential bus transceiver is a monolithic integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. It is designed for balanced transmission lines and meets ANSI Standard EIA/TIA-422-B and ITU Recommendation V.11.

The SN75176A combines a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be externally connected together to function as a direction control. The driver differential outputs and the receiver differential inputs are connected internally to form differential input/output (I/O) bus ports that are designed to offer minimum loading to the bus whenever the driver is disabled or VCC= 0. These ports feature wide positive and negative common-mode voltage ranges making the device suitable for party-line applications.
