74LVQ245 Low Voltage Octal Bidirectional Transceiver with 3-STATE Outputs February 1992 Revised June 2001 74LVQ245 Low Voltage Octal Bidirectional Transceiver with 3-STATE Outputs General Description Features The LVQ245 contains eight non-inverting bidirectional buff-Ideal for low power/low noise 3.3V applications ers with 3-STATE outputs and is intended for bus-orientedImplements patented EMI reduction circuitry applications. Current sinking capability is 12 mA at both the Available in SOIC JEDEC, SOIC EIAJ and QSOP A and B ports. The Transmit/Receive (T/R) input deter- packages mines the direction of data flow through the bidirectional Guaranteed simultaneous switching noise level and transceiver. Transmit (active-HIGH) enables data from A dynamic threshold performance ports to B ports; Receive (active-LOW) enables data from B ports to A ports. The Output Enable input, when HIGH,Improved latch-up immunity disables both A and B ports by placing them in a HIGH ZGuaranteed incident wave switching into 75Ω condition. 4 kV minimum ESD immunity Ordering Code Order Number Package Number Package Description 74LVQ245SC M20B 20-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-013, 0.300" Wide 74LVQ245SJ M20D 20-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74LVQ245QSC MQA20 20-Lead Quarter Size Outline Package (QSOP), JEDEC MO-137, 0.150" Wide Devices also available in Tape and Reel.
