SN54LVT245B and SN74LVT245B are 3.3-V ABT octal bus transceivers with 3-state outputs. They are designed using state-of-the-art BiCMOS technology for 3.3-V operation and low static-power dissipation. These devices support mixed-mode signal operation with 5-V input and output voltages using 3.3-V VCC. They also support unregulated battery operation down to 2.7 V. The typical VOLP (output ground bounce) is less than 0.8 V at VCC = 3.3 V and TA = 25°C. They provide Ioff and power-up 3-state support for hot insertion. The latch-up performance exceeds 100 mA per JESD 78, Class II. The ESD protection exceeds JESD 22 specifications, with a 2000-V human-body model (A114-A), 200-V machine model (A115-A), and 1000-V charged-device model (C101). Package options include plastic small-outline (DW), shrink small-outline (DB), and thin shrink small-outline (PW) packages, ceramic chip carriers (FK), ceramic flat (W) packages, and ceramic (J) DIPs.
The SN54LVT245B and SN74LVT245B octal bus transceivers provide bidirectional data transfer between two 8‑bit buses. They operate from a 3.3‑V supply, support 3‑state outputs for hot‑insertion, and include ESD protection meeting JESD standards.
Electrical specifications include supply voltage ranges of 0.5 V to 4.6 V, input voltage limits of –0.5 V to 7 V, low‑state output currents up to 96 mA, and operation over –55 °C to 125 °C. The devices are offered in DB, DW, PW, and ceramic packages with thermal impedances from 66 °C/W to 83 °C/W.
Yes, the transceivers are fully specified for hot‑insertion applications using power‑up 3‑state circuitry.
