The output enables are SN74ALVCH16501 18-BIT UNIVERSAL BUS TRANSCEIVER WITH 3-STATE OUTPUTS SCES024J – JULY 1995 – REVISED OCTOBER 2004 • Member of the Texas Instruments Widebus™ Family • UBT™ Transceiver Combines D-Type Latches and D-Type Flip-Flops for Operation in Transparent, Latched, or Clocked Modes • Operates From 1.65 V to 3.6 V • Max tpd of 3.9 ns at 3.3 V • ±24-mA Output Drive at 3.3 V • Bus Hold on Data Inputs Eliminates the Need for External Pullup/Pulldown Resistors • Latch-Up Performance Exceeds 250 mA Per JESD 17 • ESD Protection Exceeds JESD 22 - 2000-V Human-Body Model (A114-A) - 200-V Machine Model (A115-A) This 18-bit universal bus transceiver is designed for 1.65-V to 3.6-V VCC operation. Data flow in each direction is controlled by output-enable (OEAB and OEBA), latch-enable (LEAB and LEBA), and clock (CLKAB and CLKBA) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is high. When LEAB is low, the A data is latched if CLKAB is held at a high or low logic level. If LEAB is low, the A data is stored in the latch/flip-flop on the low-to-high transition of CLKAB. When OEAB is high, the outputs are active. When OEAB is low, the outputs are in the high-impedance state. complementary (OEAB is active high, and OEBA is active low).
