| 74HC245; 74HCT245 Octal bus tranceiver; 3-state Rev. 03 -- 31 January 2005 Product data sheet 1. General description The 74HC245; 74HCT245 is a high-speed Si-gate CMOS device and is pin compatible with Low-Power Schottky TTL (LSTTL). The 74HC245; 74HCT245 is an octal transceiver featuring non-inverting 3-state bus compatible outputs in both send and receive directions. The 74HC245; 74HCT245 features an output enable input (OE) for easy cascading and a send/receive input (DIR) for direction control. OE controls the outputs so that the buses are effectively isolated. The 74HC245; 74HCT245 is similar to the 74HC640; 74HCT640 but has true (non-inverting) outputs. 2. Features s s s s s Octal bidirectional bus interface Non-inverting 3-state outputs Multiple package options Complies with JEDEC standard no. 7A ESD protection: x HBM EIA/JESD22-A114-B exceeds 2000 V x MM EIA/JESD22-A115-A exceeds 200 V s Specified from -40 C to +85 C and from -40 C to +125 C 3.

III Product data Production [1] [2] [3] Please consult the most recently issued data sheet before initiating or completing a design. The product status of the device(s) described in this data sheet may have changed since this data sheet was published. The latest information is available on the Internet at URL http://www.semiconductors.philips.com. For data sheets describing multiple type numbers, the highest-level product status determines the data sheet status. 16. Definitions Short-form specification -- The data in a short-form specification is extracted from a full data sheet with the same type number and title. For detailed information see the relevant data sheet or data handbook. Limiting values definition -- Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 60134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information -- Applications that are described herein for any of these products are for illustrative purposes only. Philips Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or modification. 17. Disclaimers Life support -- These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips Semiconductors for any damages resulting from such application. Right to make changes -- Philips Semiconductors reserves the right to make changes in the products - including circuits, standard cells, and/or software - described or contained herein in order to improve design and/or performance. When the product is in full production (status `Production'), relevant changes will be communicated via a Customer Product/Process Change Notification (CPCN).
