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 ■ ■ ■ ■ ■ Octal bidirectional bus interface Non-inverting 3-state outputs Multiple package options Complies with JEDEC standard no. 7A ESD protection: ◆ HBM EIA/JESD22-A114-B exceeds 2000 V ◆ MM EIA/JESD22-A115-A exceeds 200 V ■ Specified from −40 °C to +85 °C and from −40 °C to +125 °C 3.
